Abstract
Barium ferrite films with high coercivity, large magnetic anisotropy, good crystal orientation and crystallinity with hexagonal symmetry have been prepared on single crystal sapphire substrates by laser in-situ deposition. The structures of these films were characterized by X-ray diffractometry. X-ray diffraction pattern shows a preferential c-axis orientation normal to the film plane at a deposition temperature of 900/spl deg/C. The magnetic properties of the films were analysed by a Vibrating Sample Magnetometer and surface morphology was measured by an Atomic Force Microscope. The thin film composition was studied by Raman spectra in qualitative manner.
