| Research Abstract |
We analyze ab initio low-energy effective models for iron-based superconductors by using many-variable variational Monte Carlo method. By analyzing five different materials, we show that the ab initio low-energy effective models successfully reproduce magnitudes of the magnetic ordered moment and magnetic-order patterns observed in iron-based superconductors. We also clarify that the iron-based superconductors are under strong influence of d Mott insulators. Furthermore, we examine the possibility of the superconductivity in electron-doped region.
