Magnetocaloric properties and critical analysis of polymorphic intermetallic compound NdIr3

Year: 2025

Type: article

Abstract: Binary intermetallic compound NdIr3 has three local minimums (for AuBe5-, AuCu3-, and PuNi3- type structures, respectively) in the formation energy landscape. The compounds with AuBe5- and PuNi3-type structure order ferromagnetically at very close Curie temperatures (T C) ≈10 K, whereas the AuCu3-type remains paramagnetic even at 2.5 K. In this report, we have investigated the detailed magnetic properties of the polymorphic NdIr3 compound, composed of AuBe5- and AuCu3-type structures. A thorough critical analysis was carried out using magnetic isotherms and specific heat behavior around its magnetic transition temperature. The values of the coefficients of critical coefficients are further verified by exploring the magnetocaloric effect results. Our investigation shows that the compound belongs to the 3D Heisenberg universal class with α = − 0.12, β = 0.34, and γ = 1.36.
