N2 - We measured the de Haas-van Alphen oscillation in divalent compounds YbTIn5 (T : Co, Rh, Ir) and YbCoGa5. The Fermi surfaces, which are characteristic in two kinds of nearly cylindrical Fermi surface, are approximately unchanged in these compounds and are well explained by the results of energy band calculations. The cyclotron mass is found to increase remarkably as the average lattice constant decreases from 5.4 Å in YbIrIn 5 to 5.2 Å in YbCoGa5: m*c = 1.1m0 in YbIrIn5 and 5.1m0 in YbCoGa 5 for dHvA branch β1, revealing a chemical pressure effect. There exists the hybridization between 4 f electrons and conduction electrons in YbCoGa5.
