GdMnO $_3$在相界附近的持续可逆相控
Persistent and Reversible Phase Control in GdMnO$_3$ near the Phase Boundary
摘要：
我们研究了正交晶系GdMnO $_3$单晶的介电性能与温度和磁场的关系。该单晶位于铁电/螺旋反铁磁相和顺电/ $A$型反铁磁相的相界附近。在该化合物中，这两相之间的强相竞争导致具有大温度和磁场强度的独特相图。基于相图，我们成功地证明了它们之间的持久和可逆的相位切换通过施加磁场。
英文摘要：
We have investigated temperature and magnetic-field dependence of dielectric properties in the orthorhombic GdMnO$_3$ single crystal which is located near the phase boundary between the ferroelectric/spiral-antiferromagnetic phase and the paraelectric/$A$-type-antiferromagnetic one. In this compound, strong phase competition between these two phases results in a unique phase diagram with large temperature and magnetic-field hystereses. Based on the phase diagram, we have successfully demonstrated the persistent and reversible phase switching between them by application of magnetic fields.
