Defect structures preceding amorphization by ion irradiations in YBa2Cu3O(7-delta)
Abstract
Transmission electron microscopy was used to investigate defect microstructures in single crystals of YBa2Cu3O(7-delta) as a function of ion irradiation dose at 300 K. Two qualitatively different defect microstructures were observed to precede amorphization. The transition between microstructures occurs at a damage level where published resistance versus temperature measurements indicate a transition from superconducting to insulating behavior.
