Control of the ferroelectricity in metastable state for orthorhombic $R$MnO${}_3$ crystals

K. Noda, M. Akaki, F. Nakamura +2

We have investigated orthorhombic $R$MnO${}_3$ ($R$=(Gd${}_{1-y}$Tb${}_y$)) crystals near the phase boundary between the paraelectric $A$-type-antiferromagnetic (AF) phase (PA) and t…
