This study is concerned with a two-dimensional electron-hole system in a strong perpendicular magnetic field with special attention devoted to the Rashba spin-orbit coupling. The influence of this interaction on the chemical potential of the Bose-Einstein condensed magnetoexcitons and on the ground state energy, and on the energy of the single-particle elementary excitations are investigated in the Hartree-Fock approximation. We demonstrate that chemical potential is monotonic function versus the value of the filling factor with negative compressibility, which leads to instability of the Bose-Einstein condensate of magnetoexcitons.
