Paper Title:
Properties of Co Substituted Bismuth Ferrite System by Rapid Liquid Phase Sintering
  Abstract

The multiferroic ceramic samples of Co substituted Bi0.9Nd0.1Fe1-xCoxO3 ( x = 0.00, 0.03, 0.05, 0.07, 0.09, 0.10, 0.20 and 0.30) were prepared by a rapid liquid phase sintering technique. As Co content increases, the Bi0.9Nd0.1Fe1-xCoxO3 samples have a structural transformation from rhombohedral (space group R3c) to cubic structure (space group I23). A small amount of Co substitution maintains the ferroelectric properties while high doping content deteriorates the ferroelectric behavior due to the attendant high leakage current caused by the valence fluctuation of Co ions. It is found that the remnant magnetization (Mr) is enhanced greatly from a value of 4.87  10-6 emu/g at x = 0.00 to 0.054 emu/g at x = 0.30.
