The magnetic properties of UMn/sub 2/were investigated for the temperature range from 360 down to 4.2 deg K. Below room temperature the magnetization curves are slightly bent toward the field axis and below 230 deg K the sample showed a small remanence. The susceptibility against temperature curve shows a lambda -type anomaly at 260 deg K and a steep increas at about 4 deg K. The hysteresis loops are not symmetrical with respect to the origin and the degree of asymmetry depends upon either the temperature or whether the sample was cooled in magnetic field or without field. From some evidence, UMn/sub 2/ is classified as an antiferromagnetic material with a small parasitic ferromagnetism which may arise from uncompensated sublaitice moments or uncompensated domain wall magnetization.
