What is Magnetic properties and magnetocaloric effect (MCE) in the rare-earths (RE) based RECu2Si2 (RE = Nd and Pr) compounds about?
RECu 2 Si 2 (RE Nd and Pr) compounds Magnetic properties A B S T R A C T The rare-earths (RE) based materials with large magnetocaloric effect (MCE) have been recently recognized as potential candidates for practical solid-state magnetic refrigeration. In this work, the two light RE-based ternary RECu 2 Si 2 (RE = Nd and Pr) compounds were fabricated by arc-melting method and investigated the structural, magnetic and magnetocaloric properties. Both RECu 2 Si 2 compounds are found to crystallize in a ThCr 2 Si 2 -type layered crystal structure with the I4/mmm space group and undergo a field-induced first-ordered magnetic transition (MT) around 13.6 and 3.5 K for NdCu 2 Si 2 and PrCu 2 Si 2 , respectively. Large reversible MCE has been observed in both RECu 2 Si 2 compounds, and the magnetocaloric parameters of the maximum isothermal magnetic entropy change (-ΔS M max ) and relative cooling power (RCP) with the magnetic field change (ΔH) of 0-7 T are determined to be 5.9 J/kg-K and 82.6 J/kg for NdCu 2 Si 2 compound and to be 8.0 J/kg-K and 67.2 J/kg for PrCu 2 Si 2 compound, respectively.
