研究了沿薄膜取向的磁场中自旋轨道（SO）相互作用对超导薄膜中临界态形成的影响。因此，考虑带间配对的情况。发现在由磁场和SO相互作用的值确定的两个参数(γ1，γ2)的平面内存在八个分支。六种模式导致具有不同脉冲 Q 值的非齐次状态。每种状态在脉冲 Q 的方向上双重简并。零温度下所有八个分支的临界点参数值均以显式形式找到。估计最佳两个分支，对应于给定 SO 相互作用的最大临界磁场值。
The effect of spin-orbit (SO) interaction on the formation of the critical states in thin superconducting films in magnetic field oriented along the film is investigated. Hereby, the case of interband pairing is considered. It was found that eight branches exist in the plane of two parameters (γ1,γ2) determined by the value of magnetic field and SO interaction. Six modes leads to inhomogeneous states with different values of the impulse Q. Each state is doubly degenerate over direction of impulse Q. The parameter values at critical point are found for all eight branches in explicit form for zero temperature. The optimal two branches are estimated, corresponding to largest critical magnetic field value for given SO interaction.
