Heavy fermion state and its superconductivity are studied using de Haas-van Alphen (dHvA) effect as well as its pressure effect. The dHvA experiment is used to detect heavy electrons in a typical heavy fermion compound CeCu. It is also extended to investigate uranium and transuranium compounds. A change of the 4f electronic state of a pressure-induced CeRhIn was studied under pressure, revealing that the superconductivity is closely related to the heavy fermion state.
