The dependence of the magnetization of high-temperature superconducting (HTSC) tapes of composition YBa2Cu3Ox (SuperOx, Moscow) on the magnetic field, temperature and orientation of the magnetic field relative to the plane of the tape has been studied. The tape magnetization values decrease by approximately two orders of magnitude when the angle of magnetic field direction relative to the plane of the tape changes from 90o (normal field orientation) to 0o (parallel orientation). It was found that in a large range of angles from 90o to 60o, the values of the magnetization component along the direction of the applied field change insignificantly. Near the parallel orientation (from 0o to 15o), the magnetization values increase approximately twofold, which is significantly less than the rate of change of magnetization in the angle range 15-60o. Keywords: High-temperature superconductor, SuperOx tape, magnetization, anisotropy, magnetic field.
