Deposition and characterization of strontium hexa ferrite (SrFe12O19) by PLD technique

KrF⁎ excimer laser (248 nm wavelength) is tightly focused on strontium hexa ferrite (SrFe12O19) to deposit its thin films on glass. Thin films were deposited at room temperature (25 °C) and at 350 °C in the absence and presence of the externally applied (0.5 T) magnetic field in transverse direction. The experiments were performed under vacuum ∼10−6 Torr. All deposited films were characterized for crystallographic structure, surface morphology, magnetic properties, and optical properties using X-Ray Diffractometer (XRD), Scanning electron microscopy (SEM), Vibrating sample magnetometer (VSM) and Spectroscopic ellipsometry (SE). The results thus obtained show that magneto-optical properties of deposited thin films have been enhanced in the presence of magnetic field.
