摘要翻译:
用有序参数描述了RMn$2$O$5$(r=y,Ho,Tb,Er,Tm)的一般磁相图,它允许不同的R和不同的控制参数具有不同的有序磁结构序列。唯象磁电耦合被用来解释为什么这些磁相中的一些也是铁电的。提出了几个新的实验,可以检验这一理论。

英文摘要:
The generic magnetic phase diagram of multiferroic RMn$_2$O$_5$ (with R=Y, Ho, Tb, Er, Tm), which allows different sequences of ordered magnetic structures for different R's and different control parameters, is described using order parameters which explicitly incorporate the magnetic symmetry. A phenomenological magneto-electric coupling is used to explain why some of these magnetic phases are also ferroelectric. Several new experiments, which can test this theory, are proposed.
