Summary of the electronic phase diagram and uniaxial pressure effect on transport data in BaFe2(As1−xPx)2. a The crystal structure of BaFe2(As1−xPx)2. The purple, silvery, and blue balls indicate Fe, As/P, and Ba positions, respectively. b The collinear AF structure of BaFe2As2, which requires orthorhombic lattice distortion. c The corresponding reciprocal space, where AF Bragg peaks occur at (1, 0, L) with L = 1, 3, …. d Schematic diagrams of the FeAs tetrahedron, showing the (As, P) height to iron plane is hAs/P = 1.304(7) Å and the nearest in plabe Fe–Fe atom distance is 2.774(2) Å, respectively, for BaFe2(As0.70P0.30)2 in 300 K. e By applying a uniaxial pressure along the c-axis, pnictogen height is hAs/P = 1.306(9) Å and the in-plane Fe–Fe atom distance increases to 2.778(3) Å correspondingly. f Temperature dependence of in-plane resistance for pressures up-to 480 MPa along the c-axis of BaFe2(As0.70P0.30)2 crystal. g The electronic phase diagram of BaFe2(As1−xPx)2, where AF, superconductivity, Fermi liquid, Non-Fermi liquid, and a QCP (red dot) are marked. The yellow and green colors represent the values of n in temperature dependence of the resistivity exponent.10 Arrow marks the position in the phase diagram of the compound measured in this work
