Frustration of Exchange-Striction Ferroelectric Ordering and Growth of Electric Polarization of Phase Separation Domains in R${}_{0.8}$Ce${}_{0.2}$Mn${}_2$O${}_5$ (R = Er, Tb) Solid Solutions

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

The effect of rare-earth ions (R = Er${}_3^{+}$, Tb${}_3^{+}$, and Ce${}_{3.75}^{+}$) on the dielectric properties and the electric polarization induced by local polar phase separation domains…
