摘要: The ferrite material with compositions Ni0.7Cu0.1Zn0.2LaxFe2−xO4 (where x = 0, 0.015, 0.025, and 0.035) was synthesized by oxalate co-precipitation method. samples were characterized thermo-gravimetric differential temperature analysis (TG–DTA), energy-dispersive X-ray (EDAX), diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), field-emission scanning electron microscopy (FE-SEM), vibrating sample magnetometer (VSM) techniques. EDAX confirmed the formation of required stoichiometric samples. cubic spinel structure presence weak ortho-ferrite phases from analysis. lattice constant all ferrites found to be increase in La3+ content. main two recognized strong absorption bands frequency range 400–600 cm−1 FTIR spectra shows well ferrite. Morphological study that grain size lies 16.23–24.21 nm. It is observed saturation magnetization magnetic moment Ni–Cu–Zn decrease
