Magneto-optical Kerr effect spectroscopy setup.

Abstract

The magneto-optic is a very old branch of physics. However, the subject is still pro- gressing, either by using magneto-optical effect in a novel ways and by developing of new materials and meta-materials. One of the key experimental technique in field of magneto-optics is a magneto-optical spectrometer, determining magneto-optical spectra. Within this work, we are building a new magneto-optical spectrometer. The spectrometer is based on the photoelastic modulator. In order to measure both Kerr rotation and Kerr ellipticity directly, PEM is of carefully calibrated and described. All the description of the setup and of the optical components is based on Jones formalism.
