The Aharonov-Bohm-type oscillations in the ballistic magnetoconductivity of an open quantum dot similar to 1 mu m in size created in the GaAs/AlGaAs heterostructure by local anode oxidation have been studied. The measurements have been performed at temperatures of 4.2 and 1.5 K, which are high enough to expect a considerable suppression of the oscillations with period h/e (in magnetic flux units.). The magnetoconductivity oscillations with a period less than the quantum h/e with respect to the magnetic field are observed at 1.5 K. The explanation is proposed on the basis of the interference of the electrons moving along the time-reversed paths inscribed into the quantum (lot that have their initial and final points at one of the contacts, i.e., corresponding to a period of h/2e.
