Asymptotic critical behaviour of amorphous Ni 80- xFe xP 14B 6 alloys
Abstract
An elaborate analysis of high-resolution magnetization data reveals that the asymptotic critical behaviour of amorphous Ni 80- xFe xP 14B 6 alloys near the paramagnetic (PM)-ferromagnetic (FM) phase transition is exactly the same as that of a three-dimensional ordered Heisenberg ferromagnet but only a small fraction of spins in them actually participates in the PM-FM transition.
