Abstract

Al and Ga-substituted Bi:DyIG films have been prepared on glass substrates by pyrolysis method. The magnetic and magneto-optical properties of Al or Ga-substituted garnet films have been investigated in detail. Al or Ga-substituted Bi:DyIG films have high coercive force and good Faraday hysteresis loops. At the wavelength of 510 nm, the Faraday rotation angle was about 8 degree(s)/micrometers for the optimum Al or Ga content of 1 or 0.7, respectively. For optimum Al and Ga content, the crystallization temperatures were about 700 and 675 degree(s)C, respectively. X-ray diffraction pattern showed that the film was polycrystalline garnet phase without preferred crystal orientation.
