Determination of the onset of bulk pinning and the low-temperature-irreversibility line inBi2Sr2CaCu2O8+δ
Physical Review B (Condensed Matter)
We report the results of dc magnetization measurements of Bi 2 Sr 2 CaCu 2 O 8ϩ␦ single crystals as a function of temperature. The evolution of the hysteresis loops with temperature is examined and the irreversibility line extracted. These loops can be scaled onto each other from 4.2 to 20 K, while the lower field part of the loops for the virgin curves continue to scale up to T c . At intermediate temperatures, the scaling is broken by the appearance of the second peak or "arrowhead" whichdoi:10.1103/physrevb.53.14594 pmid:9983260 fatcat:wiy7s6iq2jgyjikafdq7vaqgri
