Abstract

Relaxation of spin waves and domain walls in antiferromagnets has been analyzed within the framework of microscopic and phenomenological approaches. Decrement of the magnon damping and the coefficient of the domain wall viscosity are calculated. The relaxation constants of relativistic and their temperature dependencies are calculated based on comparison of the two approaches. Limitations of the phenomenological approach usability are discussed.
