## Title

- title: Dynamical visualization of attractively interacting single vortices in type-II/1
    superconducting Nb by magneto-optical imaging
  title_type: original
  lang: en

## Description

- description: "In type-II/1 superconductors, the intervortex interaction has a potential
    minimum, resulting in\r\nan attractive force at certain distances. To better understand
    this unique vortex system, in-situ\r\nobservations in high-purity Nb have been
    performed using magneto-optical imaging with singlevortex resolution. We have
    dynamically visualized the behavior of the vortices during cooling,\r\nincluding
    clustering of attractively interacting single vortices, the hopping motion of
    vortices, the\r\nformation of an Abrikosov triangular lattice, and various degrees
    of disordered states with or without\r\nclusters. From the direct observations
    of clustering vortices, a conversion temperature for the\r\nboundary between type-II/2
    and type-II/1 states is evaluated. The diverse vortex configurations\r\narise
    from the interplay of the vortex-vortex interaction, the screening current, and
    the pinning\r\npotential landscape."
