The unconventional electronic ground state of Sr₃IrRuO₇ is explored via resonant x-ray scattering techniques and angle-resolved photoemission measurements. As the Ru content approaches x=0.5 in Sr₃(Ir_1-xRu_x)₂O₇, intermediate to the J_eff=1/2 Mott state in Sr₃Ir₂O₇ and the quantum critical metal in Sr₃Ru₂O₇, a thermodynamically distinct metallic state emerges. The electronic structure of this intermediate phase lacks coherent quasiparticles, and charge transport exhibits a linear temperature dependence over a wide range of temperatures. Spin dynamics associated with the long-range antiferromagnetism of this phase show nearly local, overdamped magnetic excitations and an anomalously large energy scale of 200 meV—an energy far in excess of exchange energies present within either the Sr₃Ir₂O₇ or Sr₃Ru₂O₇ solid-solution end points. Overdamped quasiparticle dynamics driven by strong spin-charge coupling are proposed to explain the incoherent spectral features of the strange metal state in Sr₃IrRuO₇.
