Characteristics of cobalt-doped zinc oxide thin films prepared by pulsed laser deposition

Summary form only given. Spintronics is a rapidly expanding research area because of recent developments in the physics of spin-dependent phenomena in spintronic materials and their potentially exciting new applications. Diluted magnetic semiconductors (DMS) has been extensively studied for use as spintronic materials. Recently, from several predictions of the possibility of room temperature ferromagnetism, the transition-metal-doped ZnO has attracted considerable attention. In this paper, several physical properties of Co-doped ZnO films are reported.
