Correct SAF calculations in SWT? #6

Closed GiovanniKl closed 3 months ago

GiovanniKl commented 4 months ago

The calculation of SAF dispersions and free energies do no take into account the possibility to couple two different materials. The model now assumes they have the same gamma and alpha. Does this make sense when they can have different Ms, Ku, and Aex?

OndrejW commented 4 months ago

Alpha does not directly change anything in dispersion relation calculation (only in lifetime, but it does not seems very reliable in SAFs). The two different gammas significantly complicate formulation of the matrix of the two coupled LL equations and thus usually only "effective gamma" is used in the literature.

OndrejW commented 3 months ago

I propose to close this issue and for now stick to the one effective Gamma and alpha. What do you think @GiovanniKl ?

GiovanniKl commented 3 months ago

Okay. I see no problem there (if it will be mentioned in the documentation and the docstrings :D).

GiovanniKl commented 3 months ago

Closing the issue then.
