“…Including only linear disorder, the ratio between the pinning and flux flow contributions to conductivity is negative, but in systems with only point defects it is positive [12]. As observed by Kim et al [34] there exist both columnar and point pinning defects in irradiated YBCO films. Columnar pinning is expected to prevail even above the irreversibility temperature and in comparison with unirradiated films, the curve of r xy ðTÞ should shift upward in irradiated films [12].…”
