Complex anisotropy and magnetization reversal on stepped surfaces probed by the magneto-optical Kerr effect
چکیده انگلیسی

So-called split hysteresis loops have been measured for ultrathin ferromagnetic films grown on stepped surfaces. Since the shape of the loops is sensitive to the direction in which the magnetic field is applied with respect to the steps, the sample orientation against the field is particularly important. We performed systematic magneto-optical Kerr effect studies for 15 and 58 ML of Fe grown on Au(1,1,13). In view of the complex magnetic anisotropy of such systems we discuss representative hysteresis loops taken at sample orientations misaligned from the field (and laser beam) direction. In particular, the presence of a so-called low field component to the hysteresis loops is discussed and its reversed polarity is explained.


► We analyze hysteresis loops measured for ferromagnetic films grown on stepped surfaces.
► We show that the sample orientation against the field is particularly important.
► The loops are not equivalent if the easy axis is parallel or perpendicular to the steps.
► We explain how the loops depend on the field component perpendicular to the steps.
