Abstract
We have found clear evidence for 2-dimensional dislocation-mediated flux motion in a high temperature superconductor. Results of the ac-susceptibility experiment on Bi2Dr2CaCu2O8+δ are compared with theory. Good agreement is obtained using a single-parameter- fit. A very reasonable value of the mean distance between pinning defects is obtained.
