Recent studies on the isovalent phosphorous-substituted 122-type iron pnictides

Recent experiments demonstrate that isovalent doping system gives the similar phase diagram as the heterovalent doped cases: with the P-doping, the magnetic order is suppressed and the superconductivity emerges. With the help of tight-binding model calculation and self-consistent lattice Bogoliubov-de Gennes (BdG) equation calculation, we choose a minimal two-orbital model and obtain the phase diagram of BaFe2(As1-xPx)2 against the P content x, which could be qualitatively comparable with the experimental results. Besides, we will compare these results with the recent experiments shown QCP in this system.
