 abstract = {The superconducting ground state of recently discovered ZrIrSi is probed
by means of muon spin rotation and relaxation (mu SR) and resistivity
measurements. The occurrence of superconductivity at T-C = 1.7 K is
confirmed by resistivity measurements. Zero field mu SR study revealed
that below T-C there is no spontaneous magnetic field in the
superconducting state, which indicates time-reversal symmetry is
preserved in the case of ZrIrSi. From transverse field mu SR
measurement, we have estimated the superfluid density as a function of
temperature, which is described by an isotropic s-wave model with a
superconducting gap 2 Delta(0)/k(B)T(C) = 5.10(2) and indicates the
presence of strong coupling superconductivity. Ab initio electronic
structure calculation indicates that there are four bands passing
through the Fermi level, forming four Fermi surface pockets. We find
that the low-energy bands are dominated by the 4d orbitals of the
transition metal Zr, with substantially less weight from the 5d orbitals
of the Ir atoms.},
