|Title:||Grain Clusters Contribution To The Multilevel Granular Behavior In Melt-textured Yba 2cu 3o 7.d|
De Lima O.F.
|Abstract:||We report on the highly anisotropic behavior of the AC field dependence of the complex magnetic susceptibility of melt-textured grown samples of YBa 2Cu 3O 7-d. We show possible experimental evidences of the predicted grain clusters contribution to the granular behavior. We compare bulk results with those obtained from equivalent measurements performed on a-axis and c-axis YBa 2Cu 3O 7-d thin films. By applying the exponential critical state model (ECSM) we have obtained the average critical current density associated to grain clusters. © 2000 Elsevier Science B.V All rights reserved.|
