Investigation of critical behavior in the vicinity of ferromagnetic to paramagnetic phase transition in the Fe_(75)Mo_8Cu_1B_(16) alloy

摘要

The main goal of this work is to study the critical behavior in the as-quenched and annealed NANOPERM Fe75Mo8Cu1B16 alloy in the vicinity of the critical temperature T-C. The second order phase transition from ferro- to paramagnetic state was confirmed by the positive slope of Arrott plots. The critical exponents (beta, gamma, and delta) have been revealed using the Kouvel-Fisher method. Moreover, the Kouvel-Fisher analysis revealed the detailed Curie temperature for all investigated samples. Published by MP Publishing.
