Dynamic magnetic susceptibility of a two-layer film in a strong magnetic field

A theoretical study is reported of the effect of interlayer exchange coupli ng on the resonance properties of a two-layer magnetic film with "easy-axis " and "easy-plane" anisotropic layers in a strong tilted magnetic field. Th e dependence of the resonance fields on the tilting angle of the external m agnetic field to the film has been obtained, the tensor of integrated high- frequency film susceptibility has been found, and its dependence on the str ength and orientation of the external field, as well as on layer thickness, has been analyzed. The results obtained agree with the available experimen tal data. (C) 2000 MAIK "Nauka/ Interperiodica".
