Engineering One-Dimensional Quantum Stripes from Superlattices of Two-Dimensional Layered Materials
J. H. Gruenewald, J. Kim, H. S. Kim +10
One-dimensional (1D) quantum systems, which are predicted to exhibit novel states of matter in theory, have been elusive in experiment. Here we report a superlattice method of crea…
Selective growth of epitaxial Sr2IrO4 by controlling plume dimensions in pulsed laser deposition
S. S. A. Seo, J. Nichols, J. Hwang +6
We report that epitaxial Sr2IrO4 thin-films can be selectively grown using pulsed laser deposition (PLD). Due to the competition between the Ruddlesden-Popper phases of strontium i…
Giant Spin Gap and Magnon Localization in the Disordered Heisenberg Antiferromagnet Sr2Ir1-xRuxO4
Yue Cao, Xuerong Liu, Wenhu Xu +15
We study the evolution of magnetic excitations in the disordered two-dimensional antiferromagnet Sr2Ir1-xRuxO4. A gigantic magnetic gap greater than 40 meV opens at x = 0.27 and in…
Doping Evolution of Magnetic Order and Magnetic Excitations in (SrLa)IrO
Xingye Lu, D. E. McNally, M. Moretti Sala +5
We use resonant elastic and inelastic X-ray scattering at the Ir- edge to study the doping-dependent magnetic order, magnetic excitations and spin-orbit excitons in the electr…
Lattice-Tuned Magnetism of Ru4+(4d4) Ions in Single-Crystals of the Layered Honeycomb Ruthenates: Li2RuO3 and Na2RuO3
J. C. Wang, J. Terzic, T. F. Qi +7
We synthesize and study single crystals of the layered honeycomb lattice Mott insulators Na2RuO3 and Li2RuO3 with magnetic Ru4+(4d4) ions. The newly found Na2RuO3 features a nearly…
