We have succeeded in growing a high-quality single crystal of UIr with the monoclinic structure by the Czochralski pulling method in a tetra-arc furnace. UIr is a ferromagnetic compound. Its Curie temperature is 46 K and the magnetic moment is found to be oriented along the [1 0 $=1] direction by the magnetization measurement. The magnetic moment is 0.5 $mu_{rm B}$$ /U. We have observed the de Haas-van Alphen (dHvA) oscillation. All the detected branches have heavy cyclotron effective masses ranging from 9.6 to 32 . They are consistent with the electronic specific heat coefficient =48.5 mJ/Kmol.
