Abstract

Thin films of Co2MnSi (CMS) have been deposited on quartz and n-Si wafers using Pulsed Laser Deposition (PLD) by varying the deposition temperature at a fixed deposition time. A study has been done to understand how the structural and magnetic properties of CMS thin films depend on the substrates as well as on deposition substrate temperature. Without the help of any buffer/seed layer, good surfaced thin films are obtained. X-ray Diffraction represents polycrystalline peaks. In quartz, the peak intensity of the (220) phase peak increases with the substrate. In Silicon, another phase (400) is also seen that increases with the substrate temperature. The saturation magnetization is highest at 600°C growth temperature for the quartz substrate. In Silicon, we find a decrease in the saturation magnetization due to the phase transition.
