Abstract
The temperature dependence of critical current was measured after removing an applied magnetic field in Bi-Sr-Ca-Cu-O films after He ion irradiation at room temperature. The curve was remarkably different from the temperature dependence of critical current without magnetic field. The difference between the temperature dependence of critical current after removing an applied magnetic field and without magnetic field is due to the presence of pinning denters produced by irradiation.Keywords
