摘要：

Microwave-induced magnetic field oscillations of the electromotive force are observed at large filling factors in two-dimensional Corbino disks fabricated on the basis of GaAs/AlAs heterostructures. It is shown that these oscillations of the electromotive force are periodic in the inverse magnetic field and are in antiphase with oscillations of microwave photoconductivity. The experimental data are explained by the inhomogeneous distribution of the microwave field between the coaxial metal contacts to the two-dimensional electron system.
