This study aims to investigate the electric, magnetic, and magnetoelectric properties for lead zirconate titanate-cobalt ferrite particulate multiferroic composite, Pb(Zr0.52Ti0.48)O3/CoFe2O4.The composites were synthesized utilizing Pechini method thermally sintered employing a microwave oven conventional method. Two molar ratios, 80/20 50/50, of constituents' phases utilized analyze effect grain size on properties. The results X-ray diffraction (XRD) patterns indicated no formation...
It is well known that the performance of magnetoelectric properties in multiferroic materials dependent on electric poling conditions. Few reports, however, have investigated poled state effects their magnetic properties. In this paper, M-H hysteresis loops were monitored from 5 K up to room temperature, for both unpoled and 0.80{0.675[Pb(Mg1/3Nb2/3)O3-0.325PbTiO3]}-0.20[CoFe2O4] particulate composites. The study was performed samples with average grain size 0.8 µm 4.4 µm. Magnetoelectric...
This paper reports the electric, magnetic and magnetoelectric properties of particulate composites system with ferroelectric phase 0.675[Pb(Mg1/3Nb2/3)O3]−0.325[PbTiO3] CoFe2O4 prepared by Spark Plasma Sintering technique. Optimized sintering thermal annealing parameters were applied in order to achieve highly dense microstructure sub micrometric grain size distribution for both phases. The results from dielectric measurements showed a diffuse dispersive transition. P-E M-H loops revealed...
