Abstract: | In tilted magnetic fields, vortices in anisotropic superconductors form one-dimensional arrangements, called vortex chains.
We have visualized vortex chains by Bitter decoration and magneto-optical technique. The fundamental energy scale for the
attractive interaction between pancake and Josephson vortices is evaluated by observing vortex chains under various conditions.
We also explore how the vortex chains evolve when the large in-plane field is applied or when the anisotropy parameter of
the system is changed |
