Title: Anomalous Magnetoresistance due to Longitudinal Spin Fluctuations in a J eff = 1/2 Mott Semiconductor

Abstract

As a hallmark of electronic correlation, spin-charge interplay underlies many emergent phenomena in doped Mott insulators, such as high-temperature superconductivity, whereas the half-filled parent state is usually electronically frozen with an antiferromagnetic order that resists external control. We report on the observation of a positive magnetoresistance that probes the staggered susceptibility of a pseudospin-half square-lattice Mott insulator built as an artificial SrIrO 3/SrTiO 3 superlattice.
