Temperature and angular dependence of some superconducting state parameters of Lu2Fe3Si5 in two-band anisotropic Ginzburg―Landau theory

Based on the two-band anisotropic Ginzburg-Landau theory, we studied the temperature and angular dependence of the coherence length, the critical velocity of Cooper pairs and the penetration depth of the two-gap superconductor Lu2Fe3Si5. The theoretical results are agreement with the experimental da...

Description
Summary:	Based on the two-band anisotropic Ginzburg-Landau theory, we studied the temperature and angular dependence of the coherence length, the critical velocity of Cooper pairs and the penetration depth of the two-gap superconductor Lu2Fe3Si5. The theoretical results are agreement with the experimental data very well.
