The theory of ferromagnetic and spin-wave resonance in a thin film magnetized parallel to its own plane

The excitation of spin waves in a thin magnetic film magnetized parallel to its own plane is examined, commencing with a solution of the Landau-Lifschitz equation with general boundary conditions. The effects on the excitation spectrum of finite damping, finite spin fixation on the film surface, and inhomogeneous distribution of the shf field over the film thickness are examined.Translated from Izvestiya VUZ.
