Room-temperature ferromagnetism observed in Mo-doped indium oxide films.

We have investigated the magnetic properties of molybdenum-doped (0–5 wt %) indium oxide films deposited on (100) MgO substrates using pulsed-laser deposition technique. Interestingly these films were found to reveal room-temperature ferromagnetism, where the magnetization increases with Mo doping. The maximum saturation magnetization of ∼6.6 emu/cc was found for ∼5 wt % Mo doping, providing approximately five times enhancement in comparison to the undoped film. We believe that this enhancement is ascribed to the magnetic moments of Mo ions occupied in the In sites. [ABSTRACT FROM AUTHOR]
