Precessing equilibrium and overcritical solitons at a spin-flop transition
arXiv:1005.2049
Abstract
Taking into account the energy dissipation in the spin-flop phase transition induced by magnetic field in an antiferromagnet with uni-axial anisotropy, the following peculiarities of precessing ball solitons (PBS) are considered: a) the states of equilibrium precessing solitons arising in the initial phase during the phase transition; b) the states of "overcritical PBS" existing outside the region of metastability. The "overcritical" PBS may originate during disintegration of the initial phase.
