Abstract

The xNi_0.83Co_0.15Cu_0.02Fe_1.9O_4－δ (NCCF) + (1−x)PbZr_0.52Ti_0.48O₃ (PZT) particulate magneto ferroelectric composites with x = 0, 0.1, 0.2, 0.3, 0.4, 0.5 and 0.6 mole fraction were prepared by conventional ceramic double sintering method. The presence of two phases (perovskite structure of ferroelectric phase and spinal structure of ferromagnetic phase) was confirmed by X-ray diffraction. The magnetoelectric (ME) property of the particulate composites was determined at room temperature as a function of intensity of magnetic field. The temperature variation of the longitudinal modulus (L) and the internal friction (Q⁻¹) of these particulate composites at 104.3 kHz was studied in the wide temperature range 30-420 ℃. The temperature variation of the longitudinal modulus in each composition of these particulate composites showed two abrupt minima. One minimum coincided with the ferroelectric – paraelectric Curie transition temperature (θ_E) and the other with the ferromagnetic-paramagnetic Curie transition temperature (θ_M). The internal friction measurement also showed two sharp peaks in each composition corresponding to those temperatures where the minima were noticed in the temperature variation of the longitudinal modulus behaviour.
