实验和理论证明多层铜氧化物超导体CuBa_2Ca_3Cu_3 O_y（Cu-1223）中的Abrikosov晶格是由涡旋分子组成的。Cu-1223被认为是典型的多组分超导体。我们表明，在这样一个系统中的旋转自由度的涡旋分子管的轴周围产生的取向无序和取向玻璃（或晶体）相，这是从来没有在传统的涡旋晶格组成的轴对称涡旋。取向玻璃相和正交畸变取向有序相的出现是多带型多组分超导体涡旋分子晶格的普遍性质。
The Abrikosov lattice in the multilayer cuprate superconductor CuBa2Ca3Cu3Oy (Cu-1223) has been experimentally and theoretically demonstrated to be composed of vortex molecules. Cu-1223 is considered to be a typical multicomponent superconductor. We show that in such a system the rotational freedom around the axis of the vortex molecular tube generates orientational disorder and the orientational glass (or crystal) phase, which is never present in conventional vortex lattices consisting of axisymmetric vortices. The emergence of the orientational glass phase and orientational order phase with orthorhombic distortion is a general property of vortex molecule lattices of the multiband type of multicomponent superconductors.
