Abstract:
The electronic properties of the heavy metal superconductor [Formula: see text] are reported. The estimated superconducting parameters obtained from physical properties measurements indicate that [Formula: see text] is a BCS-type superconductor. Electronic band structure calculations show that Ir d-states dominate the Fermi level. A comparison of electronic band structures of [Formula: see text] and [Formula: see text] shows that the Ir-compound has a strong spin-orbit-coupling effect, which creates a complex Fermi surface.
