Effect of Cr substitution on the multiferroic properties of BiFe1 − xCrxO3 compounds

Single-phase BiFe1 − xCrxO3 (x=0x=0, 0.05 and 0.1) compounds are synthesized by a sol–gel process. The lattice parameters decrease and the magnetizations increase with the Cr content. Moreover, the magnetoelectric coupling between magnetic order and ferroelectric order at room temperature was enhanced.
