Ir 5<i>d</i>-band derived superconductivity in LaIr<sub>3</sub>
We have studied the superconducting properties of LaIr$_3$ with a rhombohedral structure using magnetization, heat capacity, and muon-spin rotation/relaxation ($\mu$SR) measurements. The zero-field cooled and field cooled susceptibility measurements exhibit a superconducting transition below $T_{\mathrm{C}}$ = 2.5 K. Magnetization measurements indicate bulk type-II superconductivity with upper critical field $\mu_0H_{\mathrm{c2}}(0)$ = …
