Abstract

Description

The torque equation of nonlinear spin dynamics is considered in the magnetostatic approximation. In this framework, exact expressions for propagator of linear magnetostatic waves in ferromagnetic film between two antennas and corresponding mutual impedance of the antennas are derived, under conditions of uniform but arbitrarily oriented static magnetization and arbitrary anisotropy. The results imply also full description of spectrum of the waves.
