The paper presents an identification method of the numerical Preisach hysteresis model, based on the digital acquisition and processing of the magnetic microstructure images, which are obtained by time-resolved magneto-optical microscopy. The statistic Preisach function is computed by the superposition of all pixels, allowing to verify the basic assumptions of Preisach hysteresis model from the...

This thesis presents the development and optimization of a surface magneto-optic Kerr effect (SMOKE) magnetometer. Our magnetometer is explained in terms of its three major parts: mechanical setup, electrical connections, and LabVIEW programming. An upgrade of the electrical system is shown to double the available applied field. Studies of the deviation angle and incident polarization direction...

Fel13TaS2 is a ferromagnetic intercalation compound. Band structure calculations show various deviations from the rigid band model. We suggest that the measured Kerr spectrum is due to four transitions with paramagnetic line shape from states situated near the Fermi level to higher lying Ta-states.

We present an imaging modality that enables detection of magnetic moments and their resulting stray fields. use wide-field employs a diamond-based magnetometer has combined magneto-optic (e.g. Kerr effect) capabilities. employ such instrument to image (stripe) domains in multilayered ferromagnetic structures.
