【 摘 要 】

An exact analytical solution is given for the critical state problem in long thin type-Il superconductor strips in a perpendicular magnetic field for the case when the critical current density j(c)(B) depends on the local induction B according to a simple three-parameter model. This model describes both isotropic superconductors with this j(c)(B) dependence, but also superconductors with anisotropic pinning with a dependence j(c)(theta) where theta is the tilt angle of the flux lines away from the normal to the specimen plane.
