Abstract

First-principles calculations of the electron–phonon coupling were performed on the cubic intermetallic compound YIn3. The electron–phonon coupling constant was found to be λep = 0.42. Using the Allen–Dynes formula with a Coulomb pseudopotential of µ∗ = 0.10, a Tc of approximately 0.77 K is obtained which is reasonably consistent with the experimentally observed temperature (between 0.8 and 1.1 K). The results indicate that conventional electron–phonon coupling is capable of producing the superconductivity in this compound.
