通过自熔法成功生长出高质量的UCoGa 5和URhGa 5单晶，并测量了电阻率、磁化率和de Hass-van Alphen（dHvA）振荡。观察到三种dHvA分支，范围从8.6 × 105到8.1 × 106 Oe，对应于封闭的费米面。UCoGa 5和URhGas被认为是半金属。回旋加速器的质量很小，范围从0.6 m0到2.9 m0。
We succeeded in growing high-quality single crystals of UCoGa5 and URhGa5 by the self-flux method and measured the electrical resistivity, magnetic susceptibility, and de Hass-van Alphen(dHvA) oscillation. Three kinds of dHvA branches were observed, ranging from 8.6x 105 to 8.1 x 106Oe, which correspond to closed Fermi surfaces. UCoGa5 and URhGas are concluded to be semimetals. The cyclotron mass is small, ranging from 0.6 m0 to 2.9 m0.
