✦ Synopsis

We have measured de Haas-van Alphen (dHvA) effect in LaGa and SmGap in magnetic field up to 80kG. An crystallograp a ular dependence of the dHvA fre ic uencies were obtained in the three principal range from 10 $ lanes in LaGa:, and in the [0 011 a G to 40 MG for both corn lane for SmGas. Observed frequencies 0.7mo for LaGa and from 0.5mo tol5mo or SmGas. The mass enhancement in SmGas indicates P ounds. 7 he cyclotron masses range from 0.3mo to that 4f electrons hybridize with conduction electrons appreciably.

We have measured the de Haas-van Alphen effect up to 15T on SmGa 2 and PrGa 2. It was found that angular dependances of low frequency branches for both compounds are very similar to that of LaGa 2 while high frequency branches in SmGa 2 are completely different from that of LaGa 2.

Angle-resolved measurements of the de Haas-van Alphen (dHvA) effect are reported in LaRu2Ge 2 which is a reference material for the ferromagnetic CeRuzGe 2. At least five dHvA branches have been observed. These results closely resemble those in CeRu2Ge2. The measured effective masses are in the rang
