We report the de Haas-van Alphen (dHvA) effect studies across the first order metamagnetic transitions in samples of CexLa 1-xRu2Si2 with x 0.16, 0.51 and 0.84. It is found that the dHvA frequency and effective mass do not change across the first order metamagnetic transition. These behaviors are in striking contrast to those observed in magnetic fields across and above the metamagnetic crossover in CeRu2Si2.
