摘要：
We have observed an oscillatory magnetoresistance effect in a two-dimensional electron gas in GaAs/AlGaAs heterojunctions subjected to a periodically modulated magnetic field generated using a striped gate electrode of ferromagnetic metal. The hysteretic part of magnetoresistance clearly shows oscillations analogous to the so-called Weiss oscillation with the phase relation predicted for the case of vector potential modulation.
