Single Crystalline Co-Doped ZnO Thin Films by Molecular Beam Epitaxy and Room Temperature Ferromagnetism
-
Abstract
Single crystalline Zn1-xCoxO thin films grown on sapphire(0001)substrates by using molecular beam epitaxy (MBE)with various Co contents of 0≤x≤0.12 were studied，and their structure，optical and magnetic properties were examined.Optical transmission measurements and ln situ XPSshow that the Co cation is incorporated into the ZnO matrix and there is no secondary phase.Room and low.temperature magnetization measurements show that the Zn1-xCoxO epilayer is ferromagnetism with T, above room temperature and show intrinsic characteristic.The magnetization of samples is increased with x(x≤0.12) monotonously.-
