摘要：

Electrical transport of the two-dimensional electron gas (2DEG) is considered in the presence of a perpendicular magnetic field(B) which is modulated weakly and periodically along one direction by -B0 sin(Kx). The magnetoresistivity exhibits novel oscillations which: 1) are 90° shifted with respect to similar oscillations discovered for a 1D electrical periodic potential, and 2) their amplitude is an order of magnitude larger than for a corresponding electrical potential modulation with strength equal to h {combining short stroke overlay}ωc0 = h {combining short stroke overlay}eB0/m*c. © 1990.
