最近的电阻数据在高Tc超导体的磁场平行于CuO层的激励下，我们解决两个关键问题的约瑟夫森涡旋相图，外观上观察到的一阶转变（FOT）曲线在中间领域的结构转变和较低的临界点的FOT线。基于平均场计算，识别了YBCO热转变曲线上的结构转变，并指出与B xc情况相比，本B xc情况更容易出现较低的临界点.
Motivated by recent resistance data in high T c superconductors under magnetic fields parallel to the CuO layers, we address two key issues on the Josephson–vortex phase diagram, an appearance of structural transitions on the observed first order transition (FOT) curve in intermediate fields and of a lower critical point of the FOT line. The structural transitions reflected on the thermal transition curve in YBCO are identified based on our mean field calculation, and it is argued that a lower critical point more easily occurs in the present B ⊥ c case compared with that in B ∥ c case.
