Title: Effect of Mn doping on the structural, morphological, optical and magnetic properties of indium tin oxide films

Abstract

We report high temperature ferromagnetism in Mn (3 - 4 at.%) doped optically transparent indium tin oxide (ITO) films prepared by a sol-gel based technique. The films showed 16 - 18 nm sized uniformly distributed particles with high phase purity. Magnetic measurements yield a coercivity Hc ~ 80 Oe and a saturation magnetization Ms ~ 0.39 μB/Mn2+ ion at 300 K with a Tc > 600 K for the 3.2% Mn doped ITO film. Magnetic force microscopy showed convincing evidence of a uniformly distributed ferromagnetic phase with well defined magnetic domains spread over hundreds of independent nanoparticles.
