摘要: The magnetic behavior of amorphous Fe 9 0 - x Mn Zr 1 (0≤x≤16) alloys has been investigated in the critical region from which we determined Curie temperature (T c ) and exponents (γ, β, δ). Detailed analysis suggests that are asymptotic independent method actual (ACR), while it strongly depends on outside ACR. Asymptotic exponent values very close to those predicted by a three-dimensional nearest-neighbor Heisenberg model. obtained results provide strong experimental evidence weak itinerant ferromagnetism.
