Observation of Negative Magnetic Hysteresis Loop in ZnO Thin Films

Observation of Negative Magnetic Hysteresis Loop in ZnO Thin Films

We report on the observation of an unusual negative magnetic hysteresis loop in ZnO thin film codoped with cobalt and aluminum (Co-Al:ZnO), while other transition-metal-doped ZnO films, such as Cu-doped ZnO and Mn-doped ZnO, exhibit normal hysteresis loops. The unusual magnetic behavior is ascribed...
