Abstract
The temperature dependence of electric voltage in Bi2Sr2Ca1Cu2Oxfilms after He ion irradiation is measured for various electric currents and magnetic fields. From the thermally activated behavior of flux lines, the activation energy and the relation between the transition temperature and the Lorentz force are obtained. The pinning energy and the critical current density in Bi2Sr2Ca1Cu2Oxsingle-phase films decrease due to He ion irradiation.
