Microscopic Derivation Of The Two-Component GinzburgLandau Functional For An Ferromagnetic Superconductor
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 10
Abstract
Phenomenological Ginzburg-Landau free energy functional with two order parameters was designed on the basis of general symmetric arguments and experimental data about the thermodynamics of UGe2 systems. Here, we develop a microscopic approach that on the basic of the mean-field theory and functional integral formalism, the two-component Ginzburg-Landau functional is established to show the correlation between the feromagnetic and triplet superconducting order parameters. The meaning of the constants encountered in the microscopic theory is clarified.
