Structural and physical properties of room temperature stable multiferroic properties of single-phase (Bi0.9La0.1)FeO3-Pb, Fe0.5Nb0.5)O-3 solid solution systems

초록

(1-x)(Bi0.9La0.1)FeO3-xPb(Fe0.5Nb0.5)O-3 (BLFO-PFNO) (x=0.2, 0.7, and 0.8), are investigated as an A-site substituted counterpart multiferroic solid solution of previous (Bi0.9La0.1)FeO3-Ba(Fe0.5Nb0.5)O-3 (BLFO-BFNO). The unique BLFO-PFNO solid solution system enables soft ferromagnetism at room temperature and macroscopic polarization with the ferroelectric domain evolution due to nanoscale ordered single grains at high composition of relaxor-type ferroelectric PFNO.
