ULTRASONIC STUDIES OF CONDUCTIVITY OF SUPERCONDUCTORS

La mesure de la constante complexe de propagation du son transversal au voisinage de la temperature critique permet de déterminer les parties réelle et imaginaire de la conduction d'un supraconducteur et leur anisotropie.The measurement of the complex constant of the transverse sound propagation near Tc permits the real and imaginary parts of the superconductor conductivity and their anisotropy to be found

NONLINEAR ACOUSTIC PROPERTIES OF CONDUCTION ELECTRONS

On a étudié expérimentalement différents types de non-linéarités se présentant dans les états normal et supraconducteur d'un métal sous l'effet du pompage ultra-sonore.Various types of nonlinearities appearing in the normal and superconducting States of the metal due to ultrasonic pumping are studied experimentally
