摘要: The magnetic isotherms in the vicinity of Curie temperature T c have been measured for single crystals ordered and disordered Fe-Pt Invar alloys under external fields up to 52.7 kOe. relative accuracy magnetization is better than 1×10 -4 . critical exponents β, γ δ were obtained from static scaling hypothesis. There a considerable difference them between alloys.
