摘要：

The irreversibility line for Hc in a single crystal specimen of Bi2Sr2CaCu2O8+Δ (Bi2212) has been determined via vanishing of hysteresis in isothermal dc magnetization measurements. The hysteresis loops (Hc) in Bi2212 appear to show signatures of two-component magnetic response in several temperature regions where the temperature dependence of irreversibility field charges sharply. It is proposed that the observed behavior may be a consequence of existence of weak links of varying strength in Bi2212. © 1995 The American Physical Society.
