[en] Magneto-optical imaging ; superconductor/ferromagnet hybrids ; magnetic flux avalanches
[en] We present a detailed quantitative magneto-optical imaging study of several superconductor/
ferromagnet hybrid structures, including Nb deposited on top of thermomagnetically patterned
NdFeB, and permalloy/niobium with erasable and tailored magnetic landscapes imprinted in the
permalloy layer. The magneto-optical imaging data is complemented with and compared to scanning Hall probe microscopy measurements. Comprehensive protocols have been developed for calibrating, testing, and converting Faraday rotation data to magnetic field maps. Applied to the acquired data, they reveal the comparatively weaker magnetic response of the superconductor from the background of larger fi elds and field gradients generated by the magnetic layer.
