We examined the current flowing through p^{+}-n junction of the lattice mismatched GaAs_{1-x}Sb_{x}/GaAs heterostructure in a transverse magnetic field at 1.8 K. We have found the appearance of current oscillations, periodic as a function of the magnetic field, that are due to the Aharonov-Bohm effect of holes passed around charged dislocations.
