摘要：

Pressure effect on the magnetic properties of intermetallic compound Ni74.6Al25.4 was investigated in pressures P up to 1.2 GPa. Spontaneous magnetic moment p(s) and Curie temperature T-C decreased linearly with applying pressure. The dp(s)/dP and dT(C)/dP were -0.995 x 10(-5) mu(B)/MPa and -4.57 x 10(-3) K/MPa, respectively. These obtained magnetic properties are analyzed on the basis of Takahashi's spin fluctuation theory for itinerant electron ferromagnets.
