Abstract
GaMnN films with 1–3% Mn deposited on Si(100) and Al2O3(0001) substrates, by the technique of nebulized spray pyrolysis by employing acetylacetonate precursors, have been characterized by X-ray diffraction, photoluminescence spectra and other techniques. The films are ferromagnetic and show magnetic hysteresis. The ferromagnetic TC increases with the Mn content, with the 3% Mn film showing a TC of ∼250 K. Anomalous Hall effect is observed below TC where the films exhibit a small negative magnetoresistance.
