Abstract

Critical phenomena in cubic helimagnets with nonequivalent magnetic atoms are investigated within the framework of the Weiss mean-field theory. The reason for the occurrence of temperature dependences of elastic moduli and the pitch of the magnetic helicoid is found, and the form of these dependences, determining the change in the conditions for the appearance of magnetic skyrmions in the type-II multiferroic Cu₂OSeO₃, is predicted.

非等效位置自旋的三次helimages磁螺旋弹性模量和周期的温度依赖性

在Weiss平均场理论的框架下，研究了非等效磁原子的立方helimages中的临界现象。发现了弹性模量和磁螺旋螺距的温度依赖关系的产生原因，并预测了这些依赖关系的形式，从而决定了ii型多铁性Cu2OSeO3中磁螺旋出现条件的变化。
