THE MAGNETIC AND STRUCTURAL-PROPERTIES OF PULSED-LASER DEPOSITED EPITAXIAL MNZN-FERRITE FILMS

The magnetic and structural properties of pulsed laser deposited MnZn- ferrite films have been examined. The results show that the uniaxial a nisotropy, ferromagnetic resonance linewidth and coercive force are st rongly influenced by the microstructure of the films, and the saturati on magnetization and first-order magnetocrystalline anisotropy constan t depend on intrinsic properties such as composition and cation site o ccupation. A comparison of bulk and film magnetic properties shows tha t the magnetic properties of the films are comparable to the bulk, whi ch makes pulsed laser deposition ferrite films a prime candidate for t hin film high-frequency microwave device applications.
