Comparison of Flux Dynamics in Two Samples of YBa2Cu3O7 with Different Pinning
Published online by Cambridge University Press: 28 February 2011
Abstract
The kinetics of magnetization in two samples of YBa2Cu3O7 prepared by different methods, are studied. Magnetization vs. time data were obtained at various temperatures for a number of applied fields. The data display (after some short period of time) logarithmic behavior and (after a sufficiently long time) exponential behavior. The pinning parameter “activation volume” was determined from the experimental data for both samples.
