The electronic properties of the heavy metal superconductor LaIr3 are reported. The estimated superconducting parameters obtained from physical properties measurements indicate that LaIr3 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 LaIr3 and LaRh3shows that the Ir-compound has a strong spinorbit-coupling effect, which creates a complex Fermi surface.
