Abstract

We investigated the v = 1 quantum Hall (QH) state in a double layer system around the commensurate (C) - incommensurate (IC) transition point. Around the phase transition, two magnetoresistance R_xx minima were observed for v = 1. The minimum observed at the lower magnetic field corresponds to the C phase and the other to the IC phase, respectively. From the temperature dependence of R_xx, we found that the miximum between the two minima remains finite even at the low temperature limit. This fact suggests that there is a dissipative phase between the C and IC states such as the theoretically predicted soliton lattice phase.
