研究了倾斜磁场中各向异性层状超导体中的涡旋间相互作用。在这种情况下，出现了Abrikosov涡（AV）和Josephson涡（JVs）的交叉晶格。形成AV和JV的扁平涡之间的相互作用产生AV线的变形。它表明，作为这种变形的结果，诱导AV之间的长距离吸引。这一现象是稠密涡链形成的原因。弱垂直磁场中的涡旋结构是涡旋链相，只有一小部分JVs被AV占据。
The intervortex interaction is investigated in very anisotropic layered superconductors in tilted magnetic field. In such a case, the crossing lattice of Abrikosov vortices (AVs) and Josephson vortices (JVs) appears. The interaction between pancake vortices, forming the AVs and JVs, produces the deformation of the AV line. It is demonstrated that, as a result of this deformation, a long range attraction between AVs is induced. This phenomenon is responsible for the dense vortex chain formation. The vortex structure in the weak perpendicular magnetic field is the vortex chain phase, where only a small part of JVs is occupied by AVs.
