説明

Single-phased Ba2YCu3O7−y pellets were sequentially irradiated with 200 keV oxygen or nitrogen ions up to 1.5×1016 m−2 at room temperature, and electrical resistance was measured as a function of temperature. The superconducting transition temperature measured with current density greater than 30 kA·m−2 was increased by the ion irradiations to about 3×1015 m−2. The zero-resistance temperature measured with 121 kA·m−2 in current density was enhanced from 88.1–89.1 K to 90.4 K by oxygen ion irradiation to 1.6×1015 m−2, and then reduced to a level obtained in the nonirradiated condition after irradiation to about 1×1016 m−2.
