Local properties of an inhomogeneous two-component correlated superconductor

The intermodulation coefficient of an inhomogeneous superconductor

The high-Tc cuprate superconductors are now believed to be intrinsically inhomogeneous. We develop a theory to describe how this inhomogeneity affects the intermodulation coefficient of such a material. We show that the continuum equations describing intermodulation in a superconducting layer with spatially varying properties are formally equivalent to those describing an inhomogeneous dielectr...

Inhomogeneous magnetism induced in a superconductor at superconductor-ferromagnet interface

We study a magnetic proximity effect at superconductor (S) ferromagnet (F ) interface. It is shown that due to an exchange of electrons between the F and S metals ferromagnetic correlations extend into the superconductor, being dependent on interface parameters. We show that ferromagnetic exchange field pair breaking effect leads to a formation of subgap bands in the S layer local density of st...

Effective medium approximation and the complex optical properties of the inhomogeneous superconductor K0.8Fe2− ySe2

The in-plane optical properties of the inhomogeneous iron-chalcogenide superconductor K0.8Fe2−ySe2 with a critical temperature Tc = 31 K have been modeled in the normal state using the Bruggeman effective medium approximation for metallic inclusions in an insulating matrix. The volume fraction for the inclusions is estimated to be 10%; however, they appear to be highly distorted, suggesting a f...
