Abstract

The magnetization measurements were carried out for polycrystalline Au₄V in magnetic fields up to 130 kOe. The spontaneous magnetic moment p_s was determined to be 0.255 μ_B/V at 4 K by high field magnetization. The magnetization process was analyzed on the basis of Takahashi’s spin fluctuation theory for weak itinerant electron ferromagnets. The characteristic parameters of the spin fluctuation were estimated to be T_A = 1.3 × 10³ K and T₀ = 2.3 × 10³ K using the data for 110–130 kOe.
