Tunneling spectra of л-GaAs/Au junctions have been measured in magnetic fields B< 140 kG at a temperature of 4.2 K. When the magnetic field В is parallel to the tunneling current /, the anomaly at a zero bias voltage changes with increasing В by a factor several times larger than in the case Bi I. Magnetooscillations and a line structure in the tunneling spectrum are also observed in the vicinity of the zero-voltage anomaly in the configuration Βϊ I.
