摘要: We report negative magnetoresistance in pulsed laser deposited single phase ZnO and Mg0.268Zn0.732O films attribute it to the presence of oxygen interstitials (Oi) zinc (Zni) as observed X-ray photoelectron spectra films. An interesting feature reduction at low temperatures large fields film is explained by taking into account localized scattering.
