The existence of new electromagnetic drift modes in nonuniform quantum magnetoplasmas is predicted. For this purpose, new dispersion relations are derived by employing the quantum magnetohydrodynamic equation for plasmas without and with ion motions. The effects of electron corrections due to quantum fluctuations, density gradients, and external magnetic field strengths on the angular wave frequencies and growth/damping rates are examined. The present analytical and numerical investigations are relevant to dense astrophysical objects.
