Exchange relaxation as the mechanism of ultrafast spin reorientation in two-sublattice ferrimagnets
V. G. Baryakhtar, V. I. Butrim, B. A. Ivanov
In the exchange approximation, an exact solution is obtained for the sublattice magnetizations evolution in a two-sublattice ferrimagnet. Nonlinear regimes of spin dynamics are fou…

Dynamics and relaxation in spin nematics
V. G. Bar'yakhtar, V. I. Butrim, A. K. Kolezhuk +1
We study dynamics and relaxation of elementary excitations (magnons) in the spin nematic (quadrupole ordered) phase of S=1 magnets. We develop a general phenomenological theory of…
