Magnetization measurements have been carried out on the Ni74Mn24Pt2 amorphous thin film in magnetic fields up to 60 kG and in the temperature range 3-175 K for both the zero-field-cooling (ZFC) and field-cooling (FC) cases. At the lowest temperatures, for the FC case, the magnetization M parallel to the cooling field significantly differs from M perpendicular to it. This anisotropy was about 10 at T = 3 K and H = 60 kG, and it disappears completely at about T = 10 K. These results suggest cluster formation of strongly correlated and localized electrons. This assertion has been supported by resistivity measurements.
