Hysteresis loops measured from the longitudinal Kerr signal (hollow circle) and transverse Kerr signal (hollow square). The hysteresis loops are corresponding to φH = 44° (a) and 46° (b), φH being the angle between the applied positive field orientation and Fe [100] axis. The azimuth angle is illustrated in the inset.
