  Numerical analysis of dark matter axion-like cloud in the vicinity of
rotating black hole has been performed. The model where axion-like scalar field
is non-trivially coupled to Maxwell field is studied in the spacetime of Kerr
black hole in uniform magnetic field and in Kerr-Newman one. The dependence of
scalar mass and black hole angular momentum on accumulation of axion dark
matter cloud was given. It was revealed that condensation of the dark matter
clouds is preferable for a very small mass of axion.
