Abstract

The authors present a study of magnetostatic volume wave (MSVW) propagation in multilayered magnetic thin films with non-collinear magnetizations. YIG/GGG/YIG structure is used. The layered film is in the (110) plane. Due to the existence of both cubic and induced in-plane uniaxial anisotropy fields in the two YIG films, the two magnetizations are not aligned with the applied DC field. Since there is an angle between the two magnetizations there is a new configuration to study MSVW propagation. It was found that the angle between the two static magnetizations and the separation distance between films strongly affect the dispersion relationship
