regarding spin wave dispersion in AFM

[Mohit Mithaliya]

Hi Serban,

                  I want to simulate spin wave dispersion in antiferromagnetic material which follow 2 sublattice model. Can we observe dispersion relation for both sublattice separately? How can i get magnetization profile for separate sublattice? 

Thank You

Mohit

Hi Mohit,

Please see Tutorial 31 on the two-sublattice model. It has a worked example for FMR in an antiferromagnet.

You have access to magnetizations on the two sublattices through M and M2 quantities.

Regards,

Serban
