Abstract
Sound propagation experiments are used to investigate the superconducting (sc) phases of Heavy Fermion (HF) compounds. Velocity measurements lead to accurate B− T phase diagrams and results for the temperature dependent attenuation of all modes in UPt 3 are presented. In addition to the strain-order parameter interaction for longitudinal modes there is a Lorentz force coupling of transverse modes to the normal electrons. It leads to a B-dependence of velocity and attenuation from which information about both London and skin penetration depth in URu 2Si 2 and UBe 13 may be obtained. In UBe 13 magnetoacoustic quantum oscillations are observed which prove the coexistence of light and heavy electrons in this compound.
