Abstract
This study investigates the electronic and superconducting properties of Ni 3 AC (A: Mg, Zn, and Cd) antiperovskites through first-principles computational methods. Importantly, Ni 3 MgC has been identified as a superconductor with a transition temperature (T c ) of 8.644 K, while Ni 3 ZnC and Ni 3 CdC exhibit T c values of 2.172 K and 3.861 K, respectively, in remarkable agreement with experimental. The electron–phonon interaction strength in these materials suggests medium-coupling superconductivity. This study provides significant insights into the mechanisms driving superconductivity in metal-carbide antiperovskites, identifying opportunities for their use in advanced technologies. • The properties of Ni 3 AC (A: Mg, Zn, Cd) superconductors were theoretically studied • The mechanism of superconductivity has been explored. • Phonons and electron–phonon interaction are studied using a linear response theory. • The calculated T c values match experimental results for the compounds studied.
