Huge quadratic magneto-optical Kerr effect and magnetization reversal in the Co2FeSi Heusler compound
Original language description
Co2FeSi( 1 0 0) films with L2(1) structure deposited onto MgO( 1 0 0) were studied using both the longitudinal and quadratic ( QMOKE) magneto-optical Kerr effect. The films exhibit a huge QMOKE signal with a maximum contribution of up to 30 mdeg, 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 coupling of second or higher order. The Co2FeSi( 1 0 0) films exhibit a rather large coercivity of 350 Oe and 70 Oe for film thicknesses of 22 nm and 98 nm, respectively. Despite the fact that the films are epitaxial, they do not provide an angular dependence of the anisotropy and the remanence in excess of 1% and 2%, respectively.
