Structural and magnetic properties of Ni0.15Mg0.1Cu0.3Zn0.45Fe2O4 ferrite prepared by NaOH-precipitation method

Optimizing the synthesis of ZnFe2O4 through chemical and physical methods: effects of the synthesis route on the phase purity, inversion, and magnetic properties of spinel zinc ferrite

“…The crystallite size increased from 23.5 nm to 38.6 nm as the calcination temperature increased from 600 °C to 900 °C, accompanied with the increase in the saturation magnetization and the decrease of the coercivity. On the other hand, Hou & Wang [42] reported an increase in the crystallite size of Ni 0.15 Mg 0.1 Cu 0.3 Zn 0.45 Fe 2 O 4 prepared by coprecipitation from 13 nm to 37 nm as the calcination temperature increased from 500 °C to 800 °C, accompanied with the increase in the saturation magnetization. In an earlier study, Wang et al [43] reported the presence of a single spinel phase in all Ni 0.15 Cu 0.2 Zn 0.65 Fe 2 O 4 samples prepared by coprecipitation and calcined at temperatures in the range 500-1200 °C.…”
