Abstract
We observed de Haas-van Alphen (dHvA) oscillations in CeRh2Si2 at 1.3GPa, higher than the quantum critical pressure pc≃1.0GPa. Three observed dHvA branches correspond to the result of the 4f-itinerant model. Their cyclotron masses are large, being 24m0, 29m0 and 31m0, about 4 times larger than the corresponding band masses.
