摘要：

The current density and local magnetic field are calculated analytically for a strip of a type-II superconductor in perpendicular magnetic field H(a) for constant critical current density. The penetrating flux front has vertical slope and the initial penetration depth, magnetization change and hysteretic losses are approximately H-a(2), approximately H-a(3) and approximately H-a(4), respectively. The analytical results differ from the widely used Bean Model and explain numerous experiments in a natural way without the assumption of a surface barrier.
