Landau-Lifschitz-Gilbert (or LLG) equation~
Fra : jamesj_jin


Dato : 27-07-02 13:44

I am going to solve a differential equation arising in micromagnetic
simulations (this is used
for example when simulating computer disks or other small magnetic
components).
In a uniform effctive magnetic field H, the variable magnetization M(t) =
(M1(t),M2(t),M3(t))T satisfies
the Landau-Lifschitz-Gilbert (or LLG) equation:

dM/dt = H ×M + a M × (H ×M). (1)

Here H(t) = (H1(t),H2(t),H3(t))T is a given effective field, anda is a
given damping parameter.
Here × is the usual vector cross product.

In addition the initial magnetization must be known:
M(0) =M0 (2)
where M0 is a given vector.

I wonder if there is some free java code out there! please help!!

thanks very much!

If you cannot program that yourself, then you are better off by
finding a computer at your educational institution with Mathematica,
and use that.

It will even plot the solution for you.

Perhaps you can use Janet: http://www.fys.dtu.dk/~janet/
