摘要：

Bi2Sr2CaCu2O8+delta (Bi-2212) single crystals have been irradiated with swift heavy ions: 0.7 GeV Kr-84, 3.8 GeV Ta-181 and 3.1 GeV Bi-209. The critical current density, J(c), deduced from the DC magnetization measurement tends to increase with the size of columnar defects. The Bose-glass behavior is observed in vortex dynamics for 3.8 GeV Ta-181 or 3.1 GeV Bi-209 ion irradiation. For Kr irradiation, however, a deviation from the Bose-glass behavior occurs. Effects of damage morphology on the pinning and vortex dynamics are discussed. (C) 2000 Elsevier Science B.V. All rights reserved.
