Abstract
We report the growth of undoped and Fe (2 and 5 at%) doped molybdenum oxide
thin films on c-plane of sapphire substrate using pulsed laser ablation. X-ray
diffraction results show that the films are oriented in (100) direction and have
monoclinic structure based on MoO2 phase as also supported by Raman
spectroscopy. The x-ray photoelectron spectroscopy reveals chemical state of Fe
is +2, which favors the substitutional occupancy of Fe ion in the MoO2 matrix.
The room temperature resistivity of all the films are very low (~100 µΩcm). The
Fe doped samples show ferromagnetic behavior at room temperature.
