Abstract

The quantum oscillation of symmetrized elastic moduli of CeRu₂ has been measured by an ultrasonic technique not only in the normal conducting state but also in the superconducting mixed state which includes the field region where a peak effect appears in the magnetization curve. The angular dependence of the oscillation frequencies for various branches in the normal state is identical to that previously obtained from a magnetic dHvA experiment by Hedo et al. The angular dependence of the quantum-oscillation amplitude is discussed in terms of the electron-phonon coupling.
