Is there commercial software available which takes the spin Hall effect into account?
I know HFSS and Comsol are popular EM solvers.
In my case, I have a piece of metal and a permanent magnet adjacent to it. Sending a current through the piece of metal creates a spin current (due to the spin Hall effect) and aligns the spins on the surface of the metal. The spin alignments diffuse into the permanent magnet and causes magnetizations to change polarity. This causes a changing magnetic field (and hence an EM wave).
I would like to simulate this behavior as a function of material properties, geometry etc.
