The features of vortex formation in narrow superconducting bridges in magnetic fields perpendicular to the film surface are studied. The dependence of the critical currents on the magnetic field is investigated. It is shown that a threshold field exists for penetration of the vortices. The critical current is a pair-breaking current in magnetic fields smaller than the threshold field. Starting with he field H/sub 1/, whose magnitude is determined by the specimen width and is described by the expression H/sub 1/approx.Phi/sub 0//..omega../sup 2/, fluctuations related to the penetration of magnetic flux vortices into the film appear in the function I/sub c/(H).
