摘要：

We analyze the magnetic properties through two-orbital Hubbard model with the spin-orbit coupling (SOC) interaction in the iron-based superconductors. With the help of the lsing approximation for the Hund's coupling between the itinerant electrons and the localized spins, we give a self-consistent account of the various magnetic orders observed in pnictides and the pairing symmetry. We also calculate the local density of states (LDOS) of the vortex state when a magnetic field is applied. The LDOS without SOC shows no resonant peak at the vortex core center in the superconducting state, while it shows an obvious resonant peak when SOC is applied. (C) 2011 Elsevier B.V.
