Annotation The influence of homogeneous axial magnetic field on energy spectrum, wave functions of electron and oscillator strengths of intra-band quantum transitions in double semiconductor (GaAs/AlxGa1 – xAs) cylindrical quantum rings is studied within the model of effective mass and rectangular potentials. It is shown that the magnetic field takes off the degeneration of energy spectrum over the magnetic quantum number and effects on the localization of the electron in nanostructure. Herein, the electron energies and oscillator strengths of intra-band quantum transitions non-monotonously depend on the induction of magnetic field.
