The structure and magnetic properties of Eu-doped BiFeO3 prepared by a solid-phase sintering method

Abstract

In this work, [Formula: see text] and Eu-doped [Formula: see text] samples were prepared by a simple solid-phase sintering method and the structure and magnetic properties were studied. The results of X-ray diffraction show that [Formula: see text] sample maintains the same rhombohedral R3c structure as [Formula: see text] sample but with a slight lattice distortion due to the Eu substitution for Bi. Compared with [Formula: see text], the [Formula: see text] sample exhibits a larger remnant magnetization and a higher Curie–Weiss temperature. These results indicate that appropriate doping with Eu is effective in improving the magnetic properties of [Formula: see text] and the solid-phase sintering method used in this study is a simple and good solid-phase sintering method to prepare [Formula: see text].
