Abstract :
Coupling mechanisms between Co0.75Fe0.25 films separated by Mn layers are investigated using Brillouin light scattering from thermal spin waves, Observed applied field and Mn thickness dependences of acoustic and optic type spin wave frequencies are discussed in terms of exchange coupling and magnetic order in the Mn
