|Title:||Universal Behavior Of Ac Susceptibility Measurements In Type-ii Superconductors|
De Lima O.F.
|Abstract:||Different χac measurements can be collapsed into a single curve if plotted against the scaling variable h(ω̄/ωj)1/σ. In this work, we tested this relation for two Nb samples and one YBCO sample. The predicted scaling law for χac was verified in the Nb samples, but an unexpected frequency dependence of σ was observed in the YBCO sample. This behavior can be explained in the framework of a more general scaling law based on the critical state model. © 2000 Elsevier Science B.V. All rights reserved.|
