Horizontal line nodes in superconducting Sr2RuO4

241_05/2004Superconductivity in Sr2RuO4 is one of the most interesting phenomena in current condensed matter physics, since it is revealed to be a triplet-pairing state. Our Editor's Choice [1] considers an important problem related to the type of order parameter in this material.

The position of line nodes on the Fermi surface, as evident from recent measurements, has been determined for various scenarios shown in the cover picture. Using these models, the temperature dependence of heat capacity and penetration depth has been calculated for easy comparison with experiments.

The first author, Grzegorz Litak, is assistant professor at Technical University of Lublin and visiting scientist at the Max Planck Institute in Dresden. He is working on the effect of disorder on correlated and exotic superconductors, nonlinear dynamics, and superconductivity in strontium ruthenate. (© 2004 WILEY-VCH Verlag GmbH & Co.
