The Effect of $f$-$d$ Magnetic Coupling in Multiferroic $R$MnO${}_3$ Crystals

Masaaki Hitomi, Mizuaki Ehara, Mitsuru Akaki +2

We have established detailed magnetoelectric phase diagrams of (Eu${}_{0.595}$Y${}_{0.405}$)${}_{1-x}$Tb${}_x$MnO${}_3$ ($0\le x\le 1$) and (Eu,Y)${}_{1-x}$Gd${}_x$MnO${}_3$ ($0\le x\le 0.69$)…
