Abstract

Ternary Rare earth transition metal alloys with 2:2:1 stoichiometry, viz. RE₂Cu₂X (RE= Rare earth, X= Cd, In, Mg) are used in the magnetic refrigeration technology due to their unique magnetic and physical properties. For more future aspect of technological applications, Gd₂Cu₂X (X= Cd, In, Mg) alloys have been preferred from RE₂Cu₂X series to study the spin polarized electronic, magnetic, and thermodynamic properties using first principal theory. The spin polarized electronic behavior of Gd₂Cu₂X (X= Cd, In, Mg) shows that Gd-f orbital electrons play main role in the electronic conduction and magnetization. Magnetic calculations show high accuracy with available experimental/theoretical literature values on these materials. Thermodynamic calculations have been carried out in the wide temperature and pressure range for the first time.
