Magnetic circular dichroism study on YIG films (original) (raw)

This study presents a detailed examination of the magnetic circular dichroism (MCD) spectra of Yttrium Iron Garnet (YIG) thin films measured over a broad temperature range from 1.8 to 300 K. Utilizing liquid phase epitaxy, the authors measured spectra in a magnetic field of 0.7 tesla, investigating the magnetooptical effects and the influence of temperature on magnetic properties. Results demonstrate that MCD shows significant variability with temperature, particularly emphasizing interactions within the two sublattices of the YIG material, thereby enhancing understanding of its magnetooptical properties.
