Abstract

Bi3Fe5O12 (BIG) magneto-optic (MO) films have been grown onto (111) and (100) gadolinium gallium garnet substrates by pulsed laser deposition (PLD). X-ray and transmission electron microscopy measurements have confirmed the epitaxial growth of the BIG films oil both substrate orientations, Faraday rotation angles of both films showed linear field dependence from - 1600 to + 1600 G and the saturated Faraday rotation angle values were similar to5 deg/ pm and similar to7.8 deg/mum for the (111) and (100) oriented films, respectively. A change in the MO contrast of both films in applied magnetic field has been observed and magnetic nux distributions have been visualised in YBa2Cu3O- , (YBCO) bulk superconductor using the (001) oriented BIG film.
