概要
- 論文の詳細を見る
Irradiation with 180 MeV Cu^<11+> ions, perpendicular to the surface of a 15-μm-thick Bi_2Sr_2CaCu_2O_8 layer, enhances the irreversibility fields and increases the values of the intragrain J_c of the superconducting material. Irradiation-induced structural damages have been observed by high-resolution electron microscopy. Crystal defects consist of long continuous cylindrical columns of highly damaged material that traverse the layer. Columns are parallel to the direction of the ion beam. Diameter values lie between 2 and 8 nm.
