文摘

CuO/ZnO nanocomposites have been synthesized by a one-step hydrothermal method. The interaction between ZnO and CuO causes a modification of electronic structure. The abnormal RTFM is discovered at the interface of CuO/ZnO. The MS can be tuned by changing the phase ratios of the CuO and ZnO. The indirect double-exchange model was employed to explain the origin of magnetism.
