Fabrication and Characterization of Magnetoelectric Ceramics by Tape-Casting Method

Abstract

The modern era is the era of new class of materials i.e., the magnetoelectric materials. These magnetoelectric material as they are called, become magnetized in an electric field and electrically polarized in a magnetic field. They are preferred because of their wide range applications. Several lead-based materials possess high magnetoelectric coefficient. but lead being toxic is not preferred. Studies are being conducted on lead free material. BNT, BT and KNN are the suitable candidates for lead free ME composites. BNT base ceramics are excellent due to its good ME properties. BNT with magnetic phase NFO is found as suitable alternate of Pb-based composites. Still no report available on BNT based ME composite film grown by tape casting method and result showed that lead free material in the form of thick/thin films possess high magnetoelectric coefficient as compared to bulk material. Tape casting technique is used to make these films.
