Describing Sr2RuO4 superconductivity in a generalized Ginzburg--Landau theory
arXiv:0807.1414 · doi:10.1016/j.physleta.2009.04.074
Abstract
We propose a simple explanation of unconventional thermodynamical and magnetic properties observed for Sr2RuO4. Actually, our two-phase model of superconductivity, based on a straight generalization of the Ginzburg-Landau theory, does predict two jumps in the heat capacity as well as a double curve for the dependence of the critical temperature on an external magnetic field. Such theoretical previsions well agree with the currently available experimental data for Sr2RuO4
