Defect-induced magnetism in undoped wide band gap oxides: Zinc vacancies in ZnO as an example

AIP Advances, 2011
To shed light on the mechanism responsible for the weak ferromagnetism in undoped wide band gap oxides, we carry out a comparative study on ZnO thin films prepared using both sol-gel and molecular beam epitaxy (MBE) methods. Compared with the MBE samples,
