Huge quadratic magneto-optical Kerr effect and magnetization reversal in the Co2FeSi Heusler compound
Co2FeSi(100) films with L21 structure deposited onto MgO(100) were studied exploiting both longitudinal (LMOKE) and quadratic (QMOKE) magneto-optical Kerr effect. The films exhibit a huge QMOKE signal with a maximum contribution of up to 30mdeg, which is the largest QMOKE signal in reflection that has been measured thus far. This large value is a fingerprint of an exceptionally large spin-orbit...
متن کاملDirect observation of half-metallicity in the Heusler compound Co2MnSi
Ferromagnetic thin films of Heusler compounds are highly relevant for spintronic applications owing to their predicted half-metallicity, that is, 100% spin polarization at the Fermi energy. However, experimental evidence for this property is scarce. Here we investigate epitaxial thin films of the compound Co2MnSi in situ by ultraviolet-photoemission spectroscopy, taking advantage of a novel mul...

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.
متن کاملDevelopment of a Surface Magneto-Optic Kerr Effect Magnetometer
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...
