Abstract 



Transport properties of a twodimensional electron gas (2DEG) are studied in the presence of a normal magnetic field B, of a weak onedimensional (1D) periodic potential modulation V(x) = V(0)cos(Kx), and of the Rashba spinorbit interaction (SOI) of strength a. For V(x) = 0 the SOI mixes the up and down spin states of neighboring Landau levels into two, unequally spaced energy branches. For V(x) not equal 0 these levels broaden into bands and their bandwidths oscillate with B. The nth level bandwidth of each series vanishes at different values of B. Relative to the IDmodulated 2DEG without SOI and one flatband condition, there are two flatband conditions that depend on a and the transport coefficients can change considerably. For weak a the Weiss oscillations show beating patterns while for strong a the Shubnikovde Haas ones axe split in two.
