- Abstract
In this paper, we have studied the critical behavior at the paramagnetic ferromagnetic (PM-FM) phase transition (PT) in GdTbHoErLa (GTHEL) alloy. Near the PM-FM PT, the usefulness of the Landau theory leads to generate isothermal magnetizations M (H , T) . Through an iterative program based on the Kouvel–Fisher method, the critical exponents have been optimized. They were found to be γ = 1.04 and β = 0.82 . Thus, the exponent at the Curie temperature δ was estimated to be 2.27 . Moreover, the critical parameters are unambiguous and reasonable, but they are not matching with the conventional universality classes.
