Electric potential of the electron sound wave: Sharp disappearance in the superconducting state
Yu. A. Avramenko, E. V. Bezuglyi, N. G. Burma +1
We study the ac electric potential induced by the electron sound wave (a perturbation of the electron distribution function propagating with the Fermi velocity) in single crystals…
Characteristics of the electric field accompanying a longitudinal acoustic wave in a metal. Anomaly in the superconducting phase
Yu. A. Avramenko, E. V. Bezuglyi, N. G. Burma +4
The temperature dependence of the amplitude and phase of the electric potential arising at a plane boundary of a conductor when a longitudinal acoustic wave is incident normally on…
Magnus force and acoustic Stewart-Tolman effect in type II superconductors
V. D. Fil, D. V. Fil, A. N. Zholobenko +5
At zero magnetic field we have observed an electromagnetic radiation from superconductors subjected by a transverse elastic wave. This radiation has an inertial origin, and is a ma…
Pinning in nonmagnetic borocarbides
A. N. Zholobenko, G. P. Mikitik, V. D. Fil +4
The field dependences of the Labush parameter in nonmagnetic borocarbides are measured by a method that does not require achieving a critical state. The expected values of the crit…
Elastic anomalies in HoNi2B2C single crystals
