Abstract
(Sr1−x Lax)3Ir2O7 undergoes a bulk insulator-to-metal transition at x ≈ 0.04. Through careful analysis of previously published data (x = 0.053, 0.061, 0.076), we find an extended region below the Debye temperature in which the resistivity appears to scale linearly with temperature. Meanwhile, resonant (in)elastic x-ray scattering data (x = 0.065) suggest a possible crossover from quantum paramagnetic to quantum critical phenomenology between 100 and 200 K. We put this into context with other results, and propose a possible phase diagram as a function of doping.
