超导Sr2RuO4的面内磁场phase diagram

In-plane magnetic field phase diagram of superconducting Sr2RuO4

V. P. Mineev

摘要:

本文发展了四带金属双组分超导态基面上临界场的Ginzburg-Landau理论。结果表明,对于典型的双组分超导态,在多带情况下,上临界场基面各向异性和相变分裂仍然存在。然而,各向异性的值可以有效地小于在单频带的情况下。讨论了结果在超导Sr_2RuO_4中的应用。

英文摘要:

We develop the Ginzburg - Landau theory of the upper critical field in the basal plane of a tetragonal multiband metal in two-component superconducting state. It is shown that typical for the two component superconducting state the upper critical field basal plane anisotropy and the phase transition splitting still exist in a multiband case. However, the value of anisotropy can be effectively smaller than in the single band case. The results are discussed in the application to the superconducting Sr2RuO4.
