We theoretically study the bilayer ν 1 quantum Hall system under an inplane magnetic field. When the in-plane field becomes strong, interlayer coherence in the system is suppressed by the field and the ground state is expected to show a phase transition from a commensurate state to an incommensurate one. We investigate a phase diagram of this system by analyzing the mode-softening properties of the random-phase-approximation excitation spectrum. The diagram indicates another phase between these ones and shows a qualitatively good agreement with the one obtained by a recent experiment.
