摘要：

The magnetic properties of the RCo4Ga (R = Ce, Pr, Gd, Tb, Dy, Y) and RCoGa4(R = Ce, Pr, Nd) compounds have been studied from 4.2 to 300 K under magnetic fields from 1 to 20 kOe. YCo4Ga, CeCo4Ga and PrCo4Ga show ferromagnetic behavior while GdCo4Ga, TbCo4Ga and DyCo4Ga compounds are ferrimagnetic. At low temperatures under 1 kOe, the RCo4Ga compounds (except GdCo4Ga and YCo4Ga) show a maximum in the magnetization versus temperature curves. Hysteresis effects are also present. The RCoGa4 compounds (R = Ce, Pr, Nd) present paramagnetic behavior down to 4.6 K.
