摘要: The magnetic properties of existing amorphous iron based materials, i.e., Fe--metalloid, Fe--early transition metals and Fe--rare earth alloys, are briefly discussed for some representative alloys. spin orientation Fe--metalloid alloys has been determined by the angular dependence hyperfine interactions. It is shown that in iron--early ferromagnetic order not long-ranged, but clusters. field distributions Fe-rich consist a high low tail. structure investigated two Fe--RE (RE = Er, Ce) For first time, coupling phenomenon amorphous/crystalline multilayers discussed.
