Critical Behavior Studies in the Vicinity of the Curie Temperature in the MnCoGe Alloy
Main Article Content
Abstract
The main goal of the present work was to study the critical behavior in the MnCoGe alloy in the vicinity of the critical temperature TC. The second-order phase transition from ferro- to paramagnetic state was preliminarily confirmed by the positive slope of the Arrott plots. The critical exponents have been revealed using the Kouvel–Fisher method and yield β = 0.474 ± 0.005, γ = 0.917 ± 0.005, and δ = 2.985 ± 0.005. The Curie temperature for the MnCoGe equals 293.3 ± 0.1 K.
