Zinc Vacancy-Induced Room-Temperature Ferromagnetism in Undoped ZnO Thin Films
Undoped ZnO thin films are prepared by polymer-assisted deposition (PAD) and treated by postannealing at different temperatures in oxygen or forming gases (95% Ar+5% H2). All the samples exhibit ferromagnetism at room temperature (RT). SQUID and positron annihilation measurements show that post-ann...
