The anti-ferromagnetism exchange interaction between Mn ions is the main reason to cause the diamagnetic properties. Magnetic properties were tested by vibrating sample magnetometer (VSM). A suitable Vo density in Zn 1-xMn xO ( x = 0.03) samples is considered to be important and has positive effect on the ferromagnetism. The number of oxygen vacancies (Vo) is varied with increasing Mn content by X-ray photoelectron spectroscopy (XPS). The distribution of Mn element was analyzed by energy dispersive X-ray analysis (EDAX). The morphological features of prepared samples were studied by scanning electron microscopy (SEM). ![]() ![]() The hexagonal wurtzite structure of ZnO was confirmed by X-ray diffraction (XRD) measurement in all prepared samples. And the intrinsic relationship between the point defects and magnetic properties were investigated. In this paper, Zn 1-xMn xO ( x = 0.00, 0.03, 0.06, and 0.09) samples were prepared through Mn-doped ZnO by using sol-gel method. ZnO dilute magnetic semiconductor (DMS) is one of the most promising materials for room temperature ferromagnetic applications.
