Magnetoelectric Effect in substituted Zinc Ferrite Lead Titanate Particulate Compsites

2012

Magnetoelectric composites containing PbTiO3 ZnFeCoO4 phases have been prepared by standard ceramic technique. The structure and morphology of the composites were examined by means of X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM). The XRD result showed that the composites consist of spinel ZnFeCoO4 phase and pervoskite PbTiO3 phase annealing at temperature 750 o C. The variation in dielectric constant with the temperature and low frequency it shows dispersion in certain frequency. The dielectric properties are strongly influenced by interface phenomenon (Maxwell Wagner) due to the local electrical inhomogeneity. The peak value of dielectric decreases with increase in temperature. Conductivity, Susceptibility and permeability have been found to vary with temperature and concentration of ferrite phase due to increase in crystalline size. The static value of magnetoelectric conversion factor (dE/dx) was measured as function of applied magnetic field. The coexistence of...

Ferroelectric–Ferromagnetic Composites Based on PZT Type Powder and Ferrite Powder

Archives of Metallurgy and Materials, 2000

A ferroelectric-ferromagnetic composites based on PZT powder have been obtained in presented work. The main aim of combination of ferroelectric and magnetic powders was to obtain material showing both electric and magnetic properties. Ferroelectric ceramic powder (in amount of 90%) was based on the doped PZT type solid solution while magnetic component of the composite was nickel-zinc ferrite Ni
