Abstract

The structure, electrical property, and magnetism of 7.5% V-doped ZnO powders that were hydrogenated annealed at 300, 500, and 700 °C have been systematically investigated. The saturation magnetization and conductivity of the V:ZnO powders increase with hydrogenated annealing temperature (Tha), and the magnetization-temperature curves transform from paramagnetism to weak ferromagnetism (∼ 10-4 μB V atom) as Tha increases. The results suggest that ferromagnetism in V:ZnO powders is highly correlated to the structural defects.
