The effect of Y3+ doping on the structural and magnetic properties of Ni0.25 Zn0.75YxFe2-xO4 [x= 0.00, 0.02, 0.04, 0.06 and 0.08] was investigated. The specimen was synthesized by conventional solid state reaction method where the sintering temperature was 1150oC for 3 hours. The structure of the specimens was inspected by XRD pattern and SEM micrographs. The XRD patterns delineate the formation of spinel type cubic structure. The lattice parameters, bulk density, X-ray density and porosity were investigated for all the samples. The SEM micrographs shows that the particles of all the composition are within 0.4 – 1.2 μm. M-H curves at room temperature exhibit the ferromagnetic behavior. The effect of Y3+ causes drastically variation on saturation magnetization (Ms), coercivity (Hc) and remanent magnetization (Mr). Moreover, the M-H curves delineate the soft ferromagnetic phenomenon which can be the reason of the acceptance of the specimen in industrial applications.
