Title: Transport and magnetotransport study of Mg doped ZnO thin films

We report negative magnetoresistance in pulsed laser deposited single phase ZnO and Mg{sub 0.268}Zn{sub 0.732}O films and attribute it to the presence of oxygen interstitials (O{sub i}) and zinc interstitials (Zn{sub i}) as observed in the X-ray photoelectron spectra of the films. An interesting feature of reduction of negative magnetoresistance at low temperatures and large fields in Mg{sub 0.268}Zn{sub 0.732}O film is observed and is explained by taking into account the localized scattering.
