Orbital anisotropy underlying the superconducting dome in BaFe${}_2$(As${}_{1-x}$P${}_x$)${}_2$ superconductors

T. Sonobe, T. Shimojima, A. Nakamura +8

We investigate the in-plane anisotropy of Fe 3d orbitals occurring in a wide temperature and composition range of BaFe2(As1-xPx)2 system. By employing the angle-resolved photoemiss…
