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