Probing vortex dynamics on a single vortex level by scanning ac-susceptibility microscopy KU Leuven
© 2017 Joris Van de Vondel. The low-frequency response of type II superconductors to electromagnetic excitations is the result of two contributions: the Meissner currents and the dynamics of quantum units of magnetic flux, known as vortices. These vortices are threedimensional elastic entities, interacting repulsively, and typically immersed in an environment of randomly distributed pinning centers. Despite the continuous progress made during ...
