چکیده انگلیسی
Magnetoelectric (ME) composites with the composition (x)PbZr0.52Ti0.48O3 + (1 â x)CoFe2O4 where x = 0.0, 0.5 and 1.0 are synthesized by ball milling method. X-ray diffraction (XRD) analysis revealed the presence of both PbZr0.52Ti0.48O3 (PZT) and CoFe2O4 (CFO) pure phases in the PZT-CFO composite. Scanning electron micrographs (SEM) showed distribution of constituent phases throughout the sample. Magnetic hysteresis loop showed ferromagnetic like behaviour of the composite with a coercive field larger than cobalt ferrite. Impedance (Zâ² and Zâ³) and electrical modulus (Mâ² and Mâ³) spectra suggested two distinct electrical responses which are observed in the temperature range of 300-370 K. These contributions are arising due to the coexistence of two relaxation processes: one is attributed to the high resistive (PZT) phase; while the second one is due to the comparatively conductive (CFO) phase in the PZT-CFO composite, respectively. The electrical conduction and dipolar relaxation are dominated by small polaron hopping (SPH) model, whereas the activation energies calculated from SPH model suggested that p-type carriers are responsible for the conduction in the PZT-CFO composite. Furthermore, ion hopping and conduction mechanism are discussed using an ac conductivity analysis.
