Abstract
Al and Be point contacts are measured to study magneto quantum oscillations in resistance as a function of potential difference applied across the contact. For one group of the contacts the amplitude of resistance oscillations in magnetic field increases with voltage and is similar to the point-contact spectrum of electron-phonon interaction. For other point contacts the magnetoresistance shows a decrease in the oscillation amplitude with increasing bias across the contact. Both the increase and the decrease in the oscillation amplitude depend nonmonotonously on energy. It has been suggested that the above effects are due to electron scattering by nonequilibrium phonons or Fermi-liquid effects in nonequilibrium electron systems.
