Our paper exploring heterostructures comprised of SrTiO3 quantum wells embedded within an SmTiO3 Mott matrix was published.  By using a combination of low energy muon relaxation measurements with polarized neutron reflectometry, we uncovered a the formation of incipient antiferromagentism in the quantum wells coincident with pseudogap formation and quantum critical magnetotransport.  This suggests that the essential physics of pseudogap states in bulk transition metal oxides can be captured in this highly controlled thin film architecture.

Our paper appeared today unveiling a unidirectional spin density wave state in electron-doped Sr2IrO4. Resonant x-ray scattering experiments were able to detect a spin modulation that forms along the Ir-Ir bond diagonal in this system once a coherent Fermi surface is established.  This forms an electronically phase separated state that mirrors the magnetic state observed in hole-doped high-Tc cuprates at very low doping levels.

Our work exploring the structural response of (Sr1-xLax)3Ir2O7 to electron doping was published in Physical Review B.  This paper resolves a structural symmetry lowering from C2/c to P21/c below a critical temperature that grows with increased La substitution.  This distortion creates two unique iridium sites within the IrO6 bilayers of this material and is a secondary structural response to the onset of the proposed charge order in this system.

Our paper exploring the evolution of the structural and electronic phases of (Sr1-xCax)2IrO4 appeared today in Physical Review B.  This study unveiled the effect of chemical pressure on the structural stability, magnetism, and insulating ground state of the spin-orbit Mott insulator Sr2IrO4.  A series of distinct structure types appear with increasing Ca-content, each suggestive of reduced electronic dimensionality and are potential hosts of unconventional magnetism.
