Probing the transverse magneto-optical Kerr effect at the nanoscale

Résumé

This article presents a theoretical formalism for a magneto-optical scanning near-field microscope (MO-SNOM) in the transverse magneto-optical Kerr effect configuration. Polarized light emitted by a nanosource is scattered by the magnetic object towards the detector. The nanosource is modelled as a circular aperture in an infinitely thin, perfectly conducting screen following the Bethe-Bouwkamp model. The theorem of reciprocity is used for calculating the detected signal in a constant-height scanning mode for a Co thin film pattern. Two magnetic distributions are investigated: the single domain and the Bloch wall.
