Abstract

rf sputtered amorphous Dy-Fe metallic films were postoxidized at a certain temperature to facilitate the synthesis of certain dysprosium iron garnet thin films. The sputtering conditions affected the composition, growth and magneto-optic properties of these films. Sputtering methods were used in various magneto-optical recording applications.

Abstract

Faraday rotation (FR) measurements are made on single crystals of europium gallium garnet (EuGaG) at 1152, 632.8, and 543.5 nm in a magnetic field up to 20 kOe applied parallel to the three main crystallographic directions in the 5-540 K temperature range. For the three wavelengths, the FR is proportional to the magnetic field and the Verdet constant V show no anisotropy, even at low temperatures, within the experimental accuracy. The experimental Verdet constants are compared to different models for paramagnetic compounds. In the visible range of the spectrum, V543.5 may be slightly affected by the proximity of Eu(super 3+) transitions. Magnetic susceptibility chi measurements are reported on the same samples in similar H-T conditions. The paramagnetic behavior of chi and V are compared as a function of temperature and wavelength.
