Polar and longitudinal magneto-optical spectroscopy of bismuth substituted yttrium iron garnet films grown by pulsed laser deposition
Original language description
Ferrimagnetic bi?h substituted yttrium iron garnet BixY3 MINUS SIGN xFe5O12 (BiYIG) films with x = 1 and 2 pulsed laser deposited onto (111) Gd3Ga5O12 (GGG) substrates were studied using magneto-optical (MO) Kerr spectroscopy in the photon energy range of 1.8-5 eV at both polar and longitudinal magnetizations. The interference at lower photon energies provided the refined film thicknesses ranging between 70 and 200 nm. The films were grown under compressive strain and displayed saturation magnetizations(?0Ms) lower than that of their bulk counterparts due to the presence of nanograins forming BiYIG layers and/or magnetically dead interface layers. The trends in the MO spectra agree with those deduced from the published permittivity tensor data for BiYIG using a transfer matrix model applied to a film (BiYIG)-substrate (GGG) system. Due to the reduced ?0Ms the predicted amplitudes are typically higher. The agreement was improved using effective medium approach or by incorporating into
