Abstract: (3700 Views)

Nickel doped CoMn ferrites with high magnetization were synthesized by double sintering solid state route with compositions of Co_0.7-xNi_xMn_0.3Fe₂O₄ with x = 0, 0.05, 0.1 and 0.15. Theoretical Cation distribution for cubic spinel ferrites was suggested on basis of electrical configuration expectations and cation site preferences. Cation distribution suggested was in good agreement with experimental results obtained from VSM and XRD. Values of theoretically calculated magnetic moment, coercivity and magnetization are in good agreement with experimental data obtained from VSM. Maximum saturation magnetization of 37.7emu/gm is obtained for sample Co_0.7Mn_0.3Fe₂O₄at magnetic field of 5K Oe. Magnetostriction was found to increase with increasing magnetic field (from 1KOe to 5KOe.) Maximum magnetostriction of 84ppm was observed for sample Co_0.7Mn_0.3Fe₂O₄at 5KOe. Maximum magnetization of magnetoelectric composites with 30% Co_0.7-xNi_xMn_0.3Fe₂O₄ – 70% PbZr_0.48Ti_0.52 was found to be 7.4 emu/g for composition with x = 0.
