摘要: Co–ZnO inhomogeneous magnetic semiconductor thin films were synthesized on the subnanometer scale by sputtering. Room temperature ferromagnetism with high magnetization was found. Large negative magnetoresistance of 11% found at room temperature, and its value increased a decrease in up to 36% 4.8 K. The mechanism for large is discussed.
