Surface induced magnetic properties in TbFe and GdCo films

View publication


Amorphous 3d-RE films are investigated by magneto-optic Kerr rotation (KR) and by threshold photoemission (TP) of spin polarized electrons. For the first time, surface and subsurface hysteresis loops have been obtained by TP. There is a significant temperature-dependent difference between TP and KR. Applications with respect to magnetooptic recording media are discussed. © 1986.
