Phase diagram and representative magnetic transport properties in R2Ir2O7. a Pyrochlore lattice structure. Orange balls depict Nd ions and green ones are Ir ions. b Schematic magnetic configuration of all-in all-out state for A domain (left) and B domain (right). Phase diagram of (Nd1-xPrx)2Ir2O7 in the plane of c temperature and external pressure, d temperature and magnetic field at 1.8 GPa. According to the previous study22, the chemical substitution of Nd ions with Pr ones effectively scales with the external pressure P, i.e., “chemical pressure”. In Fig. 1c, we apply pressure on R = Nd while the x = 0.5 composition under ambient pressure corresponds to P = 3.3 GPa. PM SM stands for paramagnetic semimetal, 4/0 WSM stands for 4-in 0-out (all-in all-out) Weyl semimetal, AIAO I for all-in all-out insulator, 3/1 WSM for 3-in 1-out Weyl semimetal, respectively. e Magnetic field dependence of Hall conductivity and longitudinal conductivity. f Magnified figures of Fig. 1e in the field range between −4 T and 4 T. Red and blue marks and lines are on field-decreasing process and on field-increasing process, respectively
