Regarding coding for LLGS equation

[RISHMA T R]

Hello everyone 

Can someone guide me in writing the code to below mentioned equation ( LLGS equation )

S1 is spin vector ,  a1, b1, a2 and b2 are the system parameters which generally depends on spin current and magnetic configurations.

Thanks in advance

Hello,

In your equation the term a1S1 and the term b1S1 disappear. Due to that, the equation becomes usual LLGS like is implemented in mumax, if S2 is equal to mp. One needs to compare with the equations in the article (https://pubs.aip.org/aip/adv/article/4/10/107133/584191/The-design-and-verification-of-MuMax3) Eqs 28-30, and maybe check the torque in an arbitrary direction but in principle. I think there is a missing factor in 29, but one can go to the original article and check your implementation.

Best regards,

Felipe

Are simulating llg in monodomain? I have done that. What is your exact aim? Is this for a project?
