摘要：

The "neutral lines" which were recently predicted to occur during flux creep in thin superconductors in a transverse magnetic field, are observed by magneto-optics in YBa2Cu3O7- strips and rectangular platelets. These stationary neutral lines or loops separate regions where the flux density increases or decreases during flux creep due to the large demagnetization field. The observations are in good agreement with theory, which is extended to rectangular specimen shape. © 1995 The American Physical Society.
