The magnetotransport properties of a ring-shaped electronic interferometer with fractional filling of a Landau level were investigated. For occupation numbers 0.6< v< 1 the Aharonov-Bohm oscillations, which correspond to the quantization of the magnetic flux through the ring area, were observed in some narrow ranges of the magnetic field. These oscillations were not observed near v= 1/2. © 7995 American Institute of Physics.
