Abstract
The influence of columnar defects introduced by the heavy-ion irradiation on the pinning parameters in YBa2Cu3O7-δ thin films was investigated. The pinning parameters n, Jcm and ΔJc were derived by fitting the experimentally obtained E-J characteristics to the theoretical curves calculated from the percolation transition model. The values of n and Jcm have been increased and the value of ΔJc has been decreased by the introduction of columnar defects.
