Macroscopic theory of the relaxation of collective excitations in disordered and noncollinear magnets
- 1. Donets Physicotechnical Institute (Ukrainian SSR)
Description
In the framework of the general hydrodynamic approach a method is proposed for describing the relaxation of low-frequency magnetic excitations in disordered spin systems and many-sublattice magnets. Expressions are obtained in terms of Goldstone fields for the dissipation function both in the exchange approximation and when allowance is made for relativistic interactions
