标题： Precessing ball solitons as dissipative structures during a phase transition in a ferromagnet

摘要： 在各向异性轴方向的磁场引起的的一阶相变过程中，铁磁体中进动球状孤子（PBS）以及垂直于主磁场的周期性磁场的作用已被分析。 在这种条件下，产生的平衡 PBS 的特性由周期性磁场的频率唯一决定，其他频率的孤子是不可能存在的。 结果表明，平衡的 PBS 实质上是在亚稳态中可能出现的“耗散结构”。 显示英文摘要

摘要： Precessing ball solitons (PBS) in a ferromagnet during the first order phase transition induced by a magnetic field directed along the axis of anisotropy, while the action of the periodic field perpendicular to the main magnetic field, have been analyzed. Under this condition, the characteristics of arising equilibrium PBS's are uniquely determined by the frequency of the periodic field, but the solitons with other frequencies are impossible. It is shown that the equilibrium PBS's are essentially the "dissipative structures" that can arise in a metastable state.
