The metamagnetic behavior, which is typical in heavy fermion compounds, is observed in UCo2Zn20 and UIr2Zn20 at Hm = 80 and 20 kOe, respectively. Reflecting the metamagnetic behavior, the magnetoresistance is suppressed in magnetic fields larger than Hm, and the corresponding A-value of a Fermi liquid relation in the electrical resistivity ρ ρ0+AT2 indicates a peak at around Hm. Pressure suppresses this behavior in UIr2Zn20.
