Effects of Flux Creep in Bulk and Single Crystals of Bi2Sr2CaCu2O8+δ Superconductor

Abstract
Low-field AC susceptibility studies of bulk and single crystals samples of Bi 2 Sr 2 CaCu 2 O 8+δ (Bi-2212) have been carried out in the frequency range up to 1 KHz.At constant AC field amplitude, the dissipative component of AC susceptibility shifts to higher temperatures with increasing AC field frequency.Moreover, the thermal activation energy (E a ) for flux creep in the crystals decreases wit...
