Pseudospin domain of ν=1 double-layer quantum Hall state near commensurate–incommensurate transition Original Research Article

We investigate the quantum Hall (QH) state at the total Landau level filling factor ν=1 in double layer systems around the commensurate (C)–incommensurate (IC) transition point. We find a broad maximum in the magnetoresistance (Rxx) between the C and IC phases. The temperature dependence of Rxx shows that the maximum remains finite when the data are extrapolated down to 0 K. This fact suggests that there is a dissipative phase between the C and IC phases such as the theoretically predicted soliton lattice phase.
