THERMODYNAMICAL PROPERTIES OF LiFeAs SUPERCONDUCTOR USING TWO BAND MODEL
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 2015, Vol 4, Issue 12
Abstract
The two band model for iron pnictide based superconductors is used in present work. Using Green’s function technique and equation of motion method, we have obtained expression for superconducting order parameter, Transition temperature, Density of state and Electronic Specific Heat. The theoretical results are then applied to LiFeAs superconductor and comparision with experimental results are made. It is found that the jump in specific heat at Tc is …, which is very close to the experimental value…. The two gap and Tc are obtained which have good agreement with the experimental results. Further it is also found that interband interaction has positive effect on Tc.
