摘要：

The dependence of higher harmonics of a magnetic susceptibility of narrow superconducting films on the amplitude of applied magnetic field is theoretically investigated. The effect of sign change for the third harmonics of AC-susceptibility is predicted when dominant contribution to hysteresis characteristics due to edge barrier is replaced by that due to bulk pinning. The condition of the barrier-to-pinning crossover of the AC susceptibility is determined for the Bean critical state model. (C) 2000 Elsevier Science B.V. All rights reserved.
