Normal State Spin Dynamics of Five-band Model for Iron-pnictides (2008)
Kariyado, Toshikaze, Ogata, Masao
Normal state spin dynamics of the recently discovered iron-pnictide superconductors is discussed by calculating spin structure factor S(q, omega) in an itinerant five-band model within RPA...
Unscreening Effect on Fe-Pnictide Superconductor (2008)
Fuseya, Yuki, Kariyado, Toshikaze, Ogata, Masao
We study a microscopic mechanism of Fe-pnictide superconductor, considering the screening effects of Coulomb interaction in addition to the conventional spin-fluctuation mechanism. It is shown that,...
