Abstract

Ball milled alloys were investigated by X-ray diffraction, magnetic measurements and Mössbauer spectroscopy. No magnetic saturation is observed up to 5 T and neither the magnetization nor the Mössbauer measurements show a well-defined phase transition but a gradual disappearance of the magnetism with increasing temperature. The hyperfine field distributions and die X-ray grain size data enable the identification of Fe atoms with magnetic moments as some atomic layers' thick surface of the nonmagnetic nanometric Fe-Al grains. The unusual magnetic behaviour is attributed to the large magnetic anisotropy of the low dimensional magnetic surfaces.
