TL;DR: In this paper, the effect of heterovalent Ca, Sr, Pb, and Ba substitution on the crystal structure, dielectric, local ferroelectric, and magnetic properties of the BiFeO3 multiferroic perovskite was studied.
Journal ArticleDOI
Synthesis and multiferroic properties of Bi0.8A0.2FeO3 (A=Ca,Sr, Pb) ceramics
V. A. Khomchenko,Dmitry A. Kiselev,Joaquim M. Vieira,Andrei L. Kholkin,M. A. Sá,Y. G. Pogorelov +5 more
TL;DR: In this article, the existence of switchable ferroelectric polarization is verified by piezoresponse force microscopy that is proven to be a useful technique in semi-insulating ferroelectrics.
Journal ArticleDOI
