摘要

Solid-state reaction technique was used to synthesize a series of Co0.3Mn0.2Zn0.5YXFe2-XO4 (0.00≤ x ≤ 0.03). A single-phased cubic spinel structure with a minimum porosity was observed for the samples sintered at 1150 °C. The minimum particle size (18.27 nm) was observed for the 3 mol% Yttrium (Y) substituted sample using TEM. FTIR spectra confirmed the metal–oxygen bonds and functional groups. All samples exhibited soft ferromagnetic behavior. The sample with Y content x = 0.03 showed maximum saturation magnetization with the minimum coercive field. Therefore, the sample with Y content x = 0.03 will be a promising template for electromagnetic shielding devices, magnetic sensors, solenoid switches for soft ferromagnetic behavior, and higher saturation magnetization.
