Abstract

The appearance of magnetization during the application of mechanical stress and the creation of elastic deformation during the application of a magnetic field are two fundamental properties of piezomagnetic materials. The symmetry of superconducting ferromagnets UGe₂, URhGe, UCoGe allows piezomagnetism. In addition to conventional piezomagnetic properties occurring in both normal and superconducting states, superconducting state of these piezomagnets has its own specificity. Unlike conventional superconductors, in uranium ferromagnets, the critical transition temperature to the superconducting state changes its value when the direction of the field changes to the opposite.

铁磁超导体中的压磁

摘要

在施加机械应力期间出现磁化和在施加磁场期间产生弹性变形是压磁材料的两个基本特性。超导铁磁体 UGe ₂、URhGe、UCoGe 的对称性允许压电磁性。除了在正常和超导状态下均会出现常规的压电特性外，这些压电磁体的超导状态还具有其自身的特异性。与传统的超导体不同，在铀铁磁体中，当场的方向变为相反时，超导状态的临界转变温度会改变其值。
