Structure and Magnetic Properties of a Class of Spinel High-entropy Oxides by Zhu, Haiyang (author);Xie, Huidong (author);Zhao, Yihan (author);Dai, Saifei (author);Li, Mingya (author);Wang, Xiaoqiang (author) is a Materials Science article available to read on EtoBox.
What is Structure and Magnetic Properties of a Class of Spinel High-entropy Oxides about?
nanocrystalline powders, have been prepared by the solution combustion synthesis method with the temperature at 550 • C, 650 • C, and 750 • C. The phase composition analysis of the samples shows that all samples are single-phase spinel structure (Fd-3 m) and the crystalline size and lattice constant increase as temperature goes up. Furthermore, magnetic hysteresis loops indicate that magnetic moment and crystallite size can be controlled through non-magnetic Al 3+ , making it possible to achieve tailorable magnetic property. XPS results show that in all HEOs, the valence of Fe is + 3, the valence of Co is + 8/ 3 (+2: +3 = 1:1), the valence of Ni is + 2, the valence of Cr is + 3, the valence of Mn is + 3. The magnetic difference between the HEOs is caused by element substitution.
