采用自熔法生长出高质量的UFeGa 5单晶，并测量了其电阻率、磁化率、磁化强度和deHaas-van Alphen（dHvA）振荡。观测到了多个dHvA分支，范围为5.4× 105 ~ 1.4× 108 Oe，这些分支与基于5 f巡游RLAPW带的理论计算结果符合得很好.回旋加速器的质量是相对较大的，范围从2.4至9.9米0。
We succeeded in growing a high-quality single crystal of UFeGa 5 by the self-flux method and measured the electrical resistivity, magnetic susceptibility, magnetization and de Haas-van Alphen (dHvA) oscillation. Many dHvA branches were observed, ranging from 5.4× 10 5 to 1.4× 10 8 Oe. These branches are in good agreement with theoretical ones based on 5f-itinerant RLAPW band calculations. The cyclotron mass is relatively large, ranging from 2.4 to 9.9 m 0.
