Anisotropy of the coherence length from critical currents in the stoichiometric superconductor LiFeAs

M. Kończykowski, C. J. van der Beek, M. A. Tanatar +4

Miniature Hall-probe arrays were used to measure the critical current densities for the three main directions of vortex motion in the stoichiometric LiFeAs superconductor. These co…
