摘要：

We study the critical behavior at the ferromagnetic phase transition of a single crystal with the composition Fe,,Pt,, in the ordered metallic state. We derive a set of critical exponents beta = 0.46, gamma = 1.28 and delta = 3.8 for the spontaneous magnetization, the susceptibility and isothermal magnetization at T-C, respectively. This set belongs to a universal fixed point for a system with long-range magnetic interactions.
