Abstract

The system under consideration was a ferromagnetic sample with a dipole–dipole interaction of particles in the absence of exchange effects, placed in a homogeneous weak magnetic field. The properties of the ferromagnet were described in the spin wave formalism. An analytical solution of systems of equations describing the dynamics of interacting magnetic moments in external fields of different orientations (longitudinal and transverse) relative to the axis of symmetry of the top was obtained and visualized.
