    "abstract": "The magnetic field distribution, the magnetic flux, and the free energy of an\nAbrikosov vortex loop near a flat surface of type--II superconductors are\ncalculated in the London approximation. The shape of such a vortex line is a\nsemicircle of arbitrary radius. The interaction of the vortex half--ring and an\nexternal homogeneous magnetic field applied along the surface is studied. The\nmagnitude of the energy barrier against the vortex expansion into\nsuperconductor is found. The possibilities of formation of an equilibrium\nvortex line determined by the structure of the applied magnetic field by\ncreating the expanding vortex loops near the surface of type--II superconductor\nare discussed.",
