Magnetization measurements have been performed on a Ni 0.45Pt0.55 alloy in the magnetic fields up to 130 kOe and in the temperature range from 5 to 280 K. The spontaneous magnetization σs(T) follows a [1-(T/TC)2]-dependence below 15 K. In the temperature range from 15 K to the Curie temperature (41.2 K), however, σs(T) decreases in proportional to [1-(T/T C)4/3]. Obtained results can be explained with a new spin fluctuation theory of Takahashi.
