dc.description.abstract | We investigated the effect of enhancement of superconducting transition temperature Tc
by nonmagnetic atom disorder in the series of filled skutterudite-related compounds (La3M4Sn13,
Ca3Rh4Sn13, Y5Rh6Sn18, Lu5Rh6Sn18; M = Co, Ru, Rh), where the atomic disorder is generated
by various defects or doping. We have shown that the disorder on the coherence length scale x in
these nonmagnetic quasiskutterudite superconductors additionally generates a non-homogeneous,
high-temperature superconducting phase with T?
c > Tc (dilute disorder scenario), while the strong
fluctuations of stoichiometry due to increasing doping can rapidly increase the superconducting
transition temperature of the sample even to the value of T?
c 2Tc (dense disorder leading
to strong inhomogeneity). This phenomenon seems to be characteristic of high-temperature
superconductors and superconducting heavy fermions, and recently have received renewed attention.
We experimentally documented the stronger lattice stiffening of the inhomogeneous superconducting
phase T?
c in respect to the bulk Tc one and proposed a model that explains the T?
c > Tc behavior in
the series of nonmagnetic skutterudite-related compounds. | pl_PL |
