Kurzfassung:
Among other magneto-optic materials bismuth substituted yttrium iron garnet (Bi x Y 1−x ) 3 Fe 5 O 12 has the highest Faraday rotation effect in visible region. Completely substituted bismuth iron garnet Bi 3 Fe 5 O 12 (BIG) films have been grown by pulsed laser deposition technique onto (111) (NdGd) 3 (ScGa) 5 O 12 single crystal with lattice constant of 12.623 Å. X-ray diffraction proves epitaxial film quality. VSM measurements yield the saturation magnetization 4π M s , = 1100 G and coercive field is about 50 Oe. Ferromagnetic resonance (FMR) method reveals perpendicular magnetic anisotropy in fabricated films. Angular measurements of FMR give the constants of uniaxial and cubic anisotropy in BIG film: K u = 5.9×10 4 erg/cm 3 and K 1 = - 6.95×10 3 erg/cm 3 . The Faraday rotation has been found to reach - 7.8 deg/µm at 630 nm.
