- Abstract
Ions substitution into spinel ferrites has attracted intensive attention on probing novel physical phenomenon as well as developing the potential fields in information technology. Herein, we focus on a series of magnetic behaviors and thermal stability of Mg(Ga
2−x Fex )O4 substitution system. The magnetic properties and microstructure of MgGa2 O4 spinel ferrites doped with Fe ions at the Ga site have been prepared and systematically investigated in this work. Accordingly, some specific experimental results and conclusions are obtained based on the characterization of structure and magnetic properties. The continuously increasing lattice constants for doping samples and considerable Rietveld fitting results manifest the high quality of the prepared sample. Furthermore, the magnetization and magnetic transition temperature are gradually improved with the increase of Fe-doping concentration. Specifically, the saturation magnetization Ms increased from 5.24 to 35.09 emu/g upon substituting. Based on the Fe substitution, a well preservation of soft magnetic behavior sustains with strengthened Ms , and also inducing some competing magnetic frustration, namely, spin glass (SG). Our discovery paves the pathway for fundamental research in enhancing magnetization and magnetic coupling of spinel ferrites, as well as developing the potential application in low-temperature chip inductors.
