The magnetic field of moving vortices in anisotropic superconductors is considered in the framework of the time-dependent London approach. It is found that, at distances large relative to the core size, the field may change sign that alludes to a nontrivial intervortex interaction which depends on the crystal anisotropy and on the speed and direction of motion. These effects are caused by the electric fields and corresponding normal currents which appear due to the moving vortex magnetic structure. We find that the motion related part of the magnetic field attenuates at large distances as $1/r^3$ unlike the exponential decay of the static vortex field. The electric field induced by the vortex motion decreases as $1/r^2$.

各向异性超导体中的移动涡流

各向异性超导体中运动涡流的磁场在与时间相关的伦敦方法的框架内被考虑。发现，在相对于核心尺寸较大的距离处，场可能会改变符号，这暗示着取决于晶体各向异性以及运动速度和方向的非平凡的涡旋相互作用。这些效应是由由于移动涡旋磁结构而出现的电场和相应的正常电流引起的。我们发现磁场的运动相关部分在远距离衰减为$1/r^3$与静态涡旋场的指数衰减不同。涡旋运动引起的电场减小为$1/r^2$.
