Paper: Overdamped Antiferromagnetic Strange Metal State in Sr3IrRuO7

April 17, 2019

Our paper exploring the electronic ground state in Sr3IrRuO7 was published today in Physical Review Letters.  Our multimodal exploration of this compound unveiled an unusual strange metal state prior to the complete collapse the spin-orbit Mott phase endemic to Sr3Ir2O7.  An incoherent Fermi surface and magnon spectrum appear, despite the presence of long-range antiferromagnetism, and are proposed to be indicative of strong spin-charge coupling in this material.
