Inosov Physical Review X 10, 021010 (2020) https://doi.org/10.1103/PhysRevX.10.021010 Abstract In contrast to magnetic order formed by electrons’ dipolar moments, ordering phenomena associated with higher-order

Doping-induced disorder and conductivity anisotropy in the spin density wave state of iron pnictides Dheeraj Kumar Singh, Yunkyu Bang Physical Review B 101, 155101 (2020) https://doi.org/10.1103/PhysRevB.101.155101 Abstract We examine the role of doped impurity atoms on the conductivity anisotropy of the spin-density wave state in iron pnictides. The conductivity is calculated in a self-consistent spin-density wave state with random impurities in a two-orbital model. We find

We propose to use the hybridization function as a convenient measure f
