 Abstract: Critical behavior in the Nd2Pt2In compound around the ferromagnetic phase transition at TC was investigated based on the magnetocaloric effect (MCE). The critical exponent values β = 0.42(6), γ = 1.25(2) and δ = 4.00(2) obtained from the magnetic entropy change at TC and the critical magnetization isotherm, M(μ0H, TC), indicated that the magnetic interactions in this compound follow two different universality classes below and above TC, which can be described in terms of the 3D-Heisenberg and 3D-Ising models, respectively. The studies by means of the conventional method using different techniques gave values of the critical exponents that are in close agreement with those derived from the MCE analysis and also confirmed two different behaviors in the ferromagnetic and paramagnetic states. © 2019 Elsevier Ltd
