A noble polar Kerr spectroscopic instrument has been developed. The magneto-Optical polar Kerr rotation, ellipticity, and optical constants can be measured over a photon energy range from 1.4 to 6.8 eV (wavelength 180 to 900 nm) in magnetic fields of up to 2 T at various temperatures from 80 to 600 K. The system is equipped with software (LabVIEW), for automatic data acquisition, analysis, and retrieval. The present equipment is built with the most up-to-date optical elements, enabling data to be obtained with an accuracy better than 0.001°for both the rotation and ellipticity over the entire photon energy range. Data thus obtained provide much information not only for the basic study of the magneto-optical effect in an ultraviolet range, but also for the exploration of new materials for highdensity magneto-optical recording.
