Research output: Contribution to journalArticlepeer-review


We report that the quantum Hall effect can be anisotropic in a two-dimensional conducting plane of the organic superconductor (TMTSF)2ClCO4 under certain conditions. When the FISDW was depinned with high current and repinned, the hysteresis around N = 3 quantum Hall state disappears anisotropically in ρxy and ρyx. It is the first result which shows the anisotropic quantum Hall effect.
