Define a computation that calculates magnetic quantities for a system

of atoms having spins.
|

This compute calculates 6 magnetic quantities.
|

This compute calculates the following 6 magnetic quantities:
|
||||
|
||||
The three first quantities are the x,y and z coordinates of the total
|
||||
magnetization.
|
||||
|
||||
The fourth quantity is the norm of the total magnetization.
|

|

The fifth quantity is the magnetic energy.
|

|

The sixth one is referred to as the spin temperature, according
|
||||
* the three first quantities are the x,y and z coordinates of the total
|
||||
magnetization,
|

* the fourth quantity is the norm of the total magnetization,

* The fifth quantity is the magnetic energy (in eV),

* The sixth one is referred to as the spin temperature, according

to the work of :ref:`(Nurdin) <Nurdin1>`.
|

The simplest way to output the results of the compute spin calculation

is to define some of the quantities as variables, and to use the thermo and

|

[Description:]
|
||||
|
||||
Define a computation that calculates magnetic quantities for a system
|
||||
of atoms having spins.
|
||||
|
||||
This compute calculates 6 magnetic quantities.
|
||||
|
||||
The three first quantities are the x,y and z coordinates of the total
|
||||
magnetization.
|
||||
|
||||
The fourth quantity is the norm of the total magnetization.
|
||||
|
||||
The fifth quantity is the magnetic energy.
|
||||
|
||||
The sixth one is referred to as the spin temperature, according
|
||||
to the work of "(Nurdin)"_#Nurdin1.
|
||||
|
||||
The simplest way to output the results of the compute spin calculation
|
||||
is to define some of the quantities as variables, and to use the thermo and
|
||||
thermo_style commands, for example:
|
||||
|
||||
compute out_mag all spin :pre
|
||||
|
||||
variable mag_z equal c_out_mag\[3\]
|
||||
variable mag_norm equal c_out_mag\[4\]
|
||||
variable temp_mag equal c_out_mag\[6\] :pre
|
||||
|
||||
thermo 10
|
||||
thermo_style custom step v_mag_z v_mag_norm v_temp_mag :pre
|
||||
|
||||
This series of commands evaluates the total magnetization along z, the norm of
|
||||
the total magnetization, and the magnetic temperature. Three variables are
|
||||
assigned to those quantities. The thermo and thermo_style commands print them
|
||||
every 10 timesteps.
|
||||
|
||||
[Output info:]
|
||||
|
||||
The array values are "intensive". The array values will be in
|
||||
metal units ("units"_units.html).
|
||||
|
||||
[Restrictions:]
|
||||
|
||||
The {spin} compute is part of the SPIN package. This compute is only
|
||||
enabled if LAMMPS was built with this package. See the "Build
|
||||

|
||||
has to be "spin" for this compute to be valid.

[Description:]
|
||||
|
||||
This fix applies a precession torque to each magnetic spin in the group.
|
||||
|
||||
Style {zeeman} is used for the simulation of the interaction
|
||||
between the magnetic spins in the defined group and an external
|
||||
magnetic field:
|
||||
|
||||
:c,image(Eqs/force_spin_zeeman.jpg)
|
||||
|
||||
with mu0 the vacuum permeability, muB the Bohr magneton (muB = 5.788 eV/T
|
||||
in metal units).
|
||||
|
||||
Style {anisotropy} is used to simulate an easy axis or an easy plane
|
||||
for the magnetic spins in the defined group:
|
||||
|
||||
:c,image(Eqs/force_spin_aniso.jpg)
|
||||
|
||||
with n defining the direction of the anisotropy, and K (in eV) its intensity.
|
||||
If K>0, an easy axis is defined, and if K<0, an easy plane is defined.
|
||||
|
||||
Style {cubic} is used to simulate a cubic anisotropy, with three
|
||||
possible easy axis for the magnetic spins in the defined group:
|
||||
|
||||
:c,image(Eqs/fix_spin_cubic.jpg)
|
||||
|
||||
with K1 and K2c (in eV) the intensity coefficients and
|
||||
n1, n2 and n3 defining the three anisotropic directions
|
||||
defined by the command (from n1x to n3z).
|
||||
For n1 = (100), n2 = (010), and n3 = (001), K1 < 0 defines an
|
||||
iron type anisotropy (easy axis along the (001)-type cube
|
||||
edges), and K1 > 0 defines a nickel type anisotropy (easy axis
|
||||
along the (111)-type cube diagonals).
|
||||
K2^c > 0 also defines easy axis along the (111)-type cube
|
||||
diagonals.
|
||||
See chapter 2 of "(Skomski)"_#Skomski1 for more details on cubic
|
||||
anisotropies.
|
||||
|
||||
In all cases, the choice of (x y z) only imposes the vector
|
||||
directions for the forces. Only the direction of the vector is
|
||||
important; it's length is ignored (the entered vectors are
|
||||
normalized).
|
||||
|
||||
Those styles can be combined within one single command line.

|
||||
|
||||
where a, b and d are the three constant coefficients defined in the associated
|
||||
"pair_coeff" command (see below for more explanations).
|
||||
|
||||
The coefficients a, b, and d need to be fitted so that the function above matches with
|
||||
the value of the exchange interaction for the N neighbor shells taken into account.
|
||||
Examples and more explanations about this function and its parameterization are reported
|
||||
in "(Tranchida)"_#Tranchida3.
|
||||
|
||||
From this exchange interaction, each spin i will be submitted
|
||||
to a magnetic torque omega, and its associated atom can be submitted to a
|
||||
force F for spin-lattice calculations (see "fix_nve_spin"_fix_nve_spin.html),
|
||||
such as:
|
||||
|
||||
:c,image(Eqs/pair_spin_exchange_forces.jpg)
|
||||
|
||||
with h the Planck constant (in metal units), and eij = (ri - rj)/|ri-rj| the unit
|
||||
vector between sites i and j.
|
||||
|
||||
More details about the derivation of these torques/forces are reported in
|
||||
"(Tranchida)"_#Tranchida3.
|
||||
|
||||
For the {spin/exchange} pair style, the following coefficients must be defined
|
||||
for each pair of atoms types via the "pair_coeff"_pair_coeff.html command as in
|
||||
the examples above, or in the data file or restart files read by the
|
||||
"read_data"_read_data.html or "read_restart"_read_restart.html commands, and
|
||||
set in the following order:
|
||||
|
||||
rc (distance units)
|
||||
a (energy units)
|
||||
b (adim parameter)
|
||||
d (distance units) :ul
|
||||
|
||||
Note that rc is the radius cutoff of the considered exchange interaction,
|
||||
and a, b and d are the three coefficients performing the parameterization
|
||||
of the function J(rij) defined above.
|
||||
|
||||
None of those coefficients is optional. If not specified, the
|
||||
{spin/exchange} pair style cannot be used.

[Description:]
|
||||
|
||||
Style {spin/neel} computes the Neel pair anisotropy model
|
||||
between pairs of magnetic spins:
|
||||
|
||||
:c,image(Eqs/pair_spin_neel_interaction.jpg)
|
||||
|
||||
where si and sj are two neighboring magnetic spins of two particles,
|
||||
rij = ri - rj is the inter-atomic distance between the two particles,
|
||||
eij = (ri - rj)/|ri-rj| is their normalized separation vector and g1,
|
||||
q1 and q2 are three functions defining the intensity of the dipolar
|
||||
and quadrupolar contributions, with:
|
||||
|
||||
:c,image(Eqs/pair_spin_neel_functions.jpg)
|
||||
|
||||
With the functions g(rij) and q(rij) defined and fitted according to
|
||||
the same Bethe-Slater function used to fit the exchange interaction:
|
||||
|
||||
:c,image(Eqs/pair_spin_exchange_function.jpg)
|
||||
|
||||
where a, b and d are the three constant coefficients defined in the
|
||||
associated "pair_coeff" command.
|
||||
|
||||
The coefficients a, b, and d need to be fitted so that the function
|
||||
above matches with the values of the magneto-elastic constant of the
|
||||
materials at stake.
|
||||
|
||||
Examples and more explanations about this function and its
|
||||
parameterization are reported in "(Tranchida)"_#Tranchida6. More
|
||||
examples of parameterization will be provided in future work.
|
||||
|
||||
From this DM interaction, each spin i will be submitted to a magnetic
|
||||
torque omega and its associated atom to a force F (for spin-lattice
|
||||
calculations only).
|
||||
|
||||
More details about the derivation of these torques/forces are reported
|
||||
in "(Tranchida)"_#Tranchida6.

** The objective of the benchmark examples in this directory
|
||||
is the following twofold:
|
||||
- verify the implementation of the LAMMPS' SPIN package by
|
||||
comparing its results to well-known analytic results, or
|
||||
to simple test problems,
|
||||
- provide users with simple comparisons, allowing them to
|
||||
better understand what is implemented in the code.
|
||||
|
||||
The LAMMPS input file (bench-*) can be modified, as well as the
|
||||
associated python script, in order to try different comparisons.
|
||||
|
||||
All scripts can be run by executing the shell script from its
|
||||
directory. Example:
|
||||
./run-bench-exchange.sh from the benchmarck_damped_exchange/
|
||||
directory.
|
||||
|
||||
** Below a brief description of the different benchmark
|
||||
problems:
|
||||
|
||||
- benchmarck_damped_precession:
|
||||
simulates the damped precession of a single spin in a magnetic
|
||||
field.
|
||||
Run as: ./run-bench-prec.sh
|
||||
Output: x, y and z components of the magnetization, and
|
||||
magnetic energy.
|
||||
|
||||
- benchmarck_damped_exchange:
|
||||
simulates two spins interacting through the exchange
|
||||
interaction. The parameters in the LAMMPS input script
|
||||
(bench-spin-precession.in) are calibrated to match the
|
||||
exchange definition in the python script (llg_exchange.py).
|
||||
Run as: ./run-bench-exchange.sh
|
||||
Output: average magnetization resulting from the damped
|
||||
precession of the two interacting spins. Also plots the
|
||||
evolution of the magnetic energy.
|
||||
|
||||
- benchmarck_langevin_precession:
|
||||
simulates a single spin in a magnetic field and in contact
|
||||
with a thermal bath, and compares the statistical averages of
|
||||
the output to the analytical result of the Langevin function.
|
||||
Run as: ./run-bench-prec.sh
|
||||
Output: statistical average of the z-component of the
|
||||
magnetization (along the applied field) and of the magnetic
|
||||
energy versus temperature. Comparison to the Langevin function
|
||||
results (computed by the python script).
|
||||
Note: This example is a reworked version of a test problem
|
||||
provided by Martin Kroger (ETHZ).
