On the field dependence of the vortex core size
V. G. Kogan, N. V. Zhelezina
We argue that in clean high- type II superconductors, the low temperature vortex core size (defined as the coherence length ) in high fields should decrease with increasing a…

Penetration depth anisotropy in two-band superconductors
V. G. Kogan, N. V. Zhelezina
The anisotropy of the London penetration depth is evaluated for two-band superconductors with arbitrary inter- and intra-band scattering times. If one of the bands is clean and the…
