摘要
The magnetization of ideal type-II superconductors without vortex pinning is derived from first principles for superconductors with constant thickness. This magnetization is irreversible due to a macroscopic geometric barrier for flux penetration at the edges, which yields a sharply defined entry field H-en. Above some reversibility field H-rev>H-en the magnetization becomes reversible and coincides with that of an ideal ellipsoid. [S0163-1829(99)04441-0].
