Abstract
We study the effect of magnetoplasmons on the drag resistance in a strong magnetic field, at finite temperatures. The typical magnetic field is about 1 T, and the temperature is up to 10 K. The Landau levels are broadened by disorder, but well separated in energy. We discuss intra-Landau level magnetoplasmons, with low frequencies, below ωc, and inter-Landau level magnetoplasmons (also called Bernstein modes), with high frequencies, close to multiples of ωc. We compare the temperature dependence of the minima and maxima of the Shubnikov-de Haas oscillations of the transresistance.
