Control of ferroelectric phase by chemical pressure in (Gd,Tb)MnO${}_3$ crystals

K. Noda, S. Nakamura, H. Kuwahara

We have investigated the dielectric properties of Gd${}_{1-x}$Tb${}_x$MnO${}_3$ crystals in magnetic fields to clarify the crossover between two distinct ferroelectric phases, GdMnO$…
