updga5的磁化和比热测量表明，在低于50 K的温度下，updga5具有反铁磁性。中子衍射研究表明，U的有序磁矩很低，可能小于0.5μB。uirga5具有弱顺磁性，磁化率约为1×10-8m3/mol。utga5化合物的弱磁性可能是由于u5f态与过渡金属Ga和d态的4p态的强杂化所致。
Magnetization and specific heat measurements on UPdGa5indicate antiferromagnetism at temperatures below 50 K. Neutron diffraction study shows, however, that the ordered magnetic moment of U should be very low (probably less than 0.5μB). UIrGa5exhibits weak paramagnetism with susceptibility values around 1×10-8m3/mol. The feeble magnetic properties of UTGa5compounds are probably due to a strong hybridization of U 5f states with 4p states of Ga and d states of the transition metal.
