Current induced oscillations of differential conductivity of two-dimension electrons, placed in quantizing magnetic fields, are observed in GaAs quantum wells in Corbino geometry. The oscillations are periodic in the square of the inverse magnetic field and occur in Corbino rings with a width which is much lesser than the radius of the rings. The conductance oscillations are described by Zener tunneling between Landau orbits in the absence of the Hall electric field. (C) 2012 American Institute of Physics.
