N2 - 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 Rxx 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 Rxx, 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.
