Abstract

We have observed the de Haas-van Alphen oscillation in LaAg and CeAg. Four kinds of closed Fermi surfaces are detected in LaAg, which are in good agreement with the results of band calculations. In CeAg, each Fermi surface is split into two Fermi surfaces with the up- and down-spin states due to the ferromagnetic exchange interaction. The cyclotron mass of CeAg is not very large, which is only by 40% larger than the corresponding mass of LaAg.
