Abstract

It is well known that the performance of magnetoelectric properties in multiferroic materials is dependent on the electric poling conditions. Few reports, however, have investigated electric poled state effects on their magnetic properties. In this paper, M-H hysteresis loops were monitored from 5 K up to room temperature, for both unpoled and poled 0.80[0.675{[}Pb(Mg1/3Nb2/3)O-3-0.325PbTiO(3)]]-0.20{[}CoFe2O4] particulate composites. The study was performed for samples with average grain size of 0.8 mu m and 4.4 mu m. Magnetoelectric voltage response was also evaluated for samples poled under 20kV/cm, 30 min., at different temperatures. The results show that the magnetic anisotropy is strengthened by remanent electric polarization, probably due to an enhancement of the strain anisotropy at the biphasic grain boundaries, which depends upon the grain size distribution.
