Anisotropy of the fluctuation component of the penetration depth in exotic superconductors
Barash Yu. S., Mel'nikov A. S., Yukhimets A. I.
Fluctuation corrections to the magnetic-field penetration depth λ of exotic superconductors are derived. These corrections give rise to a temperature dependence of the relative anisotropy of Л near Tc. Experimental observation of such a temperature dependence would be evidence for an exotic superconductivity.
