Three superconducting phases with different categories of pairing in hole- and electron-doped LaFeAs $_{1 - x}$ P $_{x}$ O

S. Miyasaka, M. Uekubo, H. Tsuji +8

The phase diagram of LaFeAs $_{1 - x}$ P $_{x}$ O system has been extensively studied through hole- and electron-doping as well as As/P-substitution. It has been revealed that there are th…
