INTERFACE MAGNETISM IN V FE(001) AND PT/FE(001)/

The magnetic properties of unoccupied electronic states in nonmagnetic metal films deposited on a clean ferromagnetic surface are studied by Inverse Photoemission excited by low-energy spin-polarised electrons. V and Pt ultrathin films grown on Fe(001) are considered as examples. Along T vith the Fe substrate majority- and minority-spin peaks, inte rface and overlayer-derived features are clearly identified in Pt/Fe(0 01). The spin polarisation dependence of the relative transitions indi cates a ferromagnetic coupling between Pt and Fe. In V/Fe(001) no over layer-induced transitions are detected. A strong attenuation of both m ajority- and minority-spin electrons passing through the V film is obs erved. This result is discussed in terms of the electron mean free pat h and its spin dependence in magnetic films.
