Abstract

The thermodynamic transition from Bose glass to Normal state in the (K, Ba)BiO₃ superconductor, induced with columnar defects, was investigated. The ac susceptibility and specific heat measurements were performed on heavy ion irradiation (HII) (K, Ba)BiO₃ single crystals with dose-equivalent matching fields. The influence of the ion irradiation dose and the relative orientation between the tracks and the external field on the superconducting transition were studied. It was observed that the introduction of columnar defects in the superconductor shifted both the irreversibility and thermodynamic transition lines to higher temperature.
