Abstract: | Penetration by Abrikosov flux lines of an isotropic hard superconductor in the critical state induced by changes in the orientation
of external magnetic field has been theoretically investigated. The analysis has been based on the microscopic nonlocal model
taking into account forces of bulk and surface pinning, alongside magnetic forces of interaction of the row of penetrating
vortices with existing flux lines, Meissner currents, and vortex images. New vortices penetrate a superconductor only when
the angle through which the field is rotated is larger than a certain critical value. It has been determined that the alignment
of entering vortices is essentially different from that of the applied magnetic field. The feasibility of detecting noncollinearity
effects is discussed.
