Abstract
In a pure type-II superconductor under a strong magnetic field every L andau level around the Fermi energy, which is significantly broadened by the pair potential at low temperatures, splits into two major magne tic subbands. Such a splitting reflects the fact that the magnetic flu x threading a unit cell in the Abrikosov lattice is one half electroni c flux quantum. This effect is predicted to be observed as a rapid 180 degrees phase shift in the de Haas-van Alphen(dHvA) oscillations just below H-c2, and is expected to be sensitive to disorder and vortex li nes motion.
