Title: Imaging antiferromagnetic domain fluctuations and the effect of atomic scale disorder in a doped spin-orbit Mott insulator

Abstract

Correlated oxides can exhibit complex magnetic patterns. Understanding how magnetic domains form in the presence of disorder and their robustness to temperature variations has been of particular interest, but atomic scale insight has been limited. We use spin-polarized scanning tunneling microscopy to image the evolution of spin-resolved modulations originating from antiferromagnetic (AF) ordering in a spin-orbit Mott insulator perovskite iridate Sr₃Ir₂O₇ as a function of chemical composition and temperature. We find that replacing only several percent of lanthanum for strontium leaves behind nanometer-scale AF puddles clustering away from lanthanum substitutions preferentially located in the middle strontium oxide layer. Thermal erasure and reentry into the low-temperature ground state leads to a spatial reorganization of the AF puddles, which nevertheless maintain scale-invariant fractal geometry in each configuration. Our experiments reveal multiple stable AF configurations at low temperature and shed light onto spatial fluctuations of the AF order around atomic scale disorder in electron-doped Sr₃Ir₂O₇.

Atomic-scale fragmentation and collapse of antiferromagnetic order in a doped Mott insulator

Journal Article Zhao, He ; Manna, Sujit ; Porter, Zach ; ... - Nature Physics

Disentangling the relationship between the insulating state with a charge gap and the magnetic order in an antiferromagnetic Mott insulator remains difficult due to inherent phase separation as the Mott state is perturbed. Measuring magnetic and electronic properties at atomic length scales would provide crucial insight, yet this is yet to be experimentally achieved. Here, we use spin-polarized scanning tunnelling microscopy (SP-STM) to visualize the periodic spin-resolved modulations originating from the antiferromagnetic order in a relativistic Mott insulator Sr₂IrO₄, and how they change as a function of doping. We find that near the insulator-to-metal transition (IMT), the long-range antiferromagnetic ordermore »« less

New insulating antiferromagnetic quaternary iridates MLa₁₀Ir₄O₂₄ (M=Sr, Ba)

Journal Article Zhao, Qingbiao ; Han, Fei ; Stoumpos, Constantinos C. ; ... - Scientific Reports

Recently, oxides of Ir4+ have received renewed attention in the condensed matter physics community, as it was reported that certain such iridates have a strongly spin-orbital coupled (SOC) electronic state, Jeff=½. As a consequence, the critical ratio of bandwidth to Coulomb repulsion, W/U, in these extended solids lies close to unity, with an ensuing Mott insulating ground state. The canonical example for such physics is the Ruddlesden-Popper compound Sr2IrO4, which has been suggested as a potential route to a new class of high temperature superconductor due to the formal analogy between Jeff = ½ and the S = ½ statemore »« less

Correlation Effects and Hidden Spin-Orbit Entangled Electronic Order in Parent and Electron-Doped Iridates ${Sr}_{2} {IrO}_{4}$

Journal Article Zhou, Sen ; Jiang, Kun ; Chen, Hua ; ... - Physical Review. X

Analogs of the high-T_c cuprates have been long sought after in transition metal oxides. Because of the strong spin-orbit coupling, the 5d perovskite iridates Sr₂IrO₄ exhibit a low-energy electronic structure remarkably similar to the cuprates. Whether a superconducting state exists as in the cuprates requires understanding the correlated spin-orbit entangled electronic states. Recent experiments discovered hidden order in the parent and electron-doped iridates, some with striking analogies to the cuprates, including Fermi surface pockets, Fermi arcs, and pseudogap. Here, we study the correlation and disorder effects in a five-orbital model derived from the band theory. We find that the experimentalmore »« less

Polymorphous band structure model of gapping in the antiferromagnetic and paramagnetic phases of the Mott insulators MnO, FeO, CoO, and NiO

Journal Article Trimarchi, Giancarlo ; Wang, Zhi ; Zunger, Alex - Physical Review. B

The existence of band gaps in both the antiferromagnetic (AFM) and paramagnetic (PM) phases of the classic NaCl-structure Mott insulators MnO, FeO, CoO, and NiO is traditionally viewed and taught as a manifestation of strong correlation whereby insulation results from electrons moving across the lattice forming states with doubly occupied d orbitals on certain atomic sites and empty d orbitals on other sites. Within such theories, the gap of the AFM and PM phases of these oxides emerges even in the absence of spatial symmetry breaking. The need for such a correlated picture is partially based on the known failuremore »« less

First-order melting of a weak spin-orbit mott insulator into a correlated metal

Journal Article Hogan, Tom ; Yamani, Z. ; Walkup, D. ; ... - Physical Review Letters

Herein, the electronic phase diagram of the weak spin-orbit Mott insulator (Sr_1-xLa_x)₃Ir₂O₇ is determined via an exhaustive experimental study. Upon doping electrons via La substitution, an immediate collapse in resistivity occurs along with a narrow regime of nanoscale phase separation comprised of antiferromagnetic, insulating regions and paramagnetic, metallic puddles persisting until x≈0.04. Continued electron doping results in an abrupt, first-order phase boundary where the Néel state is suppressed and a homogenous, correlated, metallic state appears with an enhanced spin susceptibility and local moments. In conclusion, as the metallic state is stabilized, a weak structural distortion develops and suggests a competingmore »« less
