Description |
Highly oriented thin films of Fe3O4 were deposited on (100) LaAlO3 substrates by pulsed laser ablation. The structural quality of the films was confirmed by X-ray diffraction (XRD). The films showed a Verwey transition near 120 K. The films were subjected to 80 keV Ar+ implantation at different ion doses up to a maximum of 6 x 10(14) ions/cm(2). Ion beam induced modifications in the films were investigated using XRD and resistance vs temperature measurements. Implantation decreases the change in resistance at 120 K and this effect saturates beyond 3 x 10(14) ions/cm(2). The Yerwey transition temperature, T-v, shifts towards lower temperatures with increase in ion dose.
