Nature of magnetic excitations in superconducting BaFe1.9Ni0.1As2
試料: 単結晶
方法: 中性子非弾性散乱
結論: The common theme in both classes of high temperature superconductors is that magnetic excitations have partly localized
character, thus showing the importance of strong correlations for high temperature superconductivity
U(1) Slave-spin theory and its application to Mott transition in a multi-orbital model
for iron pnictides
理論の論文
結論: 金属に対して軌道選択的にモット状態
(有限な大きさの配位場分裂)を与えた状態も基底状態としてありうる。
