Measurements of magnetization, specific heat, neutron diffraction, and electrical resistivity at ambient and applied pressure have been carried out on the cubic compound UIr{sub 2}Zn{sub 20}. A first-order-like ferromagnetic transition occurs at T{sub C} = 2.1 K with a saturation magnetization {mu}{sub sat}-0.4{mu}{sub B}, indicating itinerant ferromagnetism. In this ordered state, the electronic specific heat coefficient remains large, {gamma}-450 mJ/mol K{sup 2}, classifying UIr{sub 2}Zn{sub 20} as one of the very few heavy-fermion ferromagnets.
