Room-temperature ferromagnetism (RTFM) remains challenging to achieve in ZnO-based dilute magnetic semiconductors (DMS) co-doped with transition metals because of complex defect interactions. To explain the non-linear magnetization behavior of hydrogenated Zn0.25Co0.75O:H specimen is reported here. The specimen was made by a solid-state process and was hydrogenated at 550 °C for 12 hours. The room temperature magnetic hysteresis was measured with a Vibrating Sample Magnetometer (VSM) and analyzed by non-linear least squares fitting in MATLAB based proposed rational model. The optimized model parameters, i.e., βSE = 0.3782, φI = – 0.0222, and δd = 2.4433, indicate increased magnetic saturation, weak inhibitive behavior, and high damping associated with oxygen vacancy-type defects, respectively. The results provide support to the rational model as a powerful approach to describe defect-induced ferromagnetism and provide guidelines to the design and optimization of spintronic materials presenting magnetic ordering at room temperature. |
