Data for Paper "Different pressure effects in A(2)Ir(2)O(7) (A = Gd, Eu, and Sm)"

The re-sistivity measurements were performed using the conventionalfour-probe method with the temperature varied using a closed-cycle helium refrigeration unit. The hydrostatic high-pressure re-sistivity measurements were carried out using a clamp-type piston pressure cell and employed Daphne 7373 oil as the medium totransmit pressure with a high level of high homogeneity. To cali-brate the pressures at room temperature, we used Cu2O powder asa manometer, whose nuclear quadrupole resonance frequency as afunction of pressure has been determined very accurately.
