Abstract
Magnetic resonance frequencies in a magnetic trilayer or superlattice are theoretically studied. Biquadratic exchange between layers is assu med to be sufficiently strong for non-collinear (canted) magnetic orde ring to exist in the multilayer. The optic mode frequency turns out to vanish at the boundary between antiferromagnetic and canted states. I t is shown that in the case of longitudinal pumping one can observe th e resonance at two different values of magnetic field strength.
