| dc.description | We have developed a real space spin-parallel theory of superconductivity based on the minimum principle in energy. This theory has successfully provided coherent explanations to a number of complicated problems in conventional and non-conventional superconductors. In this paper, we report the study the optimal doping problem in the new oxypnictide high-temperature superconductors using aforementioned theory. In FeAs family, it is shown that there are three optimum (or quasi-optimum) doped phases at doping levels x1=1/3, 1/6 and 1/8, where the vortex lattice forms square or triangular stable configurations. While in Fe2As2 family, the optimal dopings occur at x2=2/5 and 1/2 with square and triangular superconducting vortex line lattices, respectively. | |
