Anomalous magnetoresistance due to longitudinal spin fluctuations in a J eff = 1/2 Mott semiconductor

Anomalous magnetoresistance due to longitudinal spin fluctuations in a J eff = 1/2 Mott semiconductor

Spin-charge interactions are at the core of electronic correlation phenomena in Mott insulators. Here, the authors observe a positive anomalous magnetoresistance in a SrIrO3/SrTiO3 superlattice, indicative of strong spin-charge fluctuations in this pseudospin-half square-lattice Mott insulator.
