DC susceptibility χ (χ = M/H) data for U(Ga_{0.95}Mn_{0.05})_{3} measured in the FC (closed symbols) mode and the ZFC (open symbols) mode in various magnetic fields. T_{a} is denoted by the temperature where χ_{ZFC}(T) reaches a maximum and T_{ir} is the temperature where χ_{FC}(T) and χ_{ZFC}(T) start to separate from each other. T_{m} is defined as the temperature where the susceptibility sharply increases. The inset displays the temperature dependence of the inverse molar magnetic susceptibility.
