Electric polarization induced by phase separation in magnetically ordered and paramagnetic states of RMn2O5 (R=Gd, Bi)

B. Kh. Khannanov, V. A. Sanina, E. I. Golovenchits +1

The electric polarization hysteresis loops and remanent polarization were revealed in multiferroics RMn${}_2$O${}_5$ with $R=Gd$ and $Bi$ at wide temperature interval from 5 K up to…
