✦ Synopsis

Frequency-dependent ac shielding measurements are used to elucidate the origin of magnetic irreversibility in heavy-ion irradiated Bi~Sr~CaCu208 single crystals. Whereas at intermediate static fields B < B,, ac response is well described by Bose-glass dynamics, low field response is probably governed by a surface barrier.

In the present work we report the results of studying the influence of the uranium-ion irradiation of the Bi 2 Sr 2 CaCu 2 O 8 thin films on the high-temperature part (close to T c ) of their irreversibility line. We studied irreversible properties of the films by measuring the hysteresis of nonreso
