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

Abstract

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 state of the cuprate superconductors. The quest for other iridium oxides that present tests of the underlying SOC physics is underway. Here we report the synthesis and physical properties of two new quaternary tetravalent iridates, MLa10Ir4O24 (M = Sr, Ba). The crystal structure of both compounds features isolated IrO6 octahedra in which the electronic configuration of Ir is d5. Both compounds are antiferromagnetic, and resistivity measurement shows that SrLa10Ir4O24 is an insulator. By isolating the octahedra and thus eliminating bandwidth and super-exchange as a competing influence on the electronic structure, compounds such as these can provide a platform for testing themore »« less

Synthesis and electronic properties of Ruddlesden-Popper strontium iridate epitaxial thin films stabilized by control of growth kinetics

Journal Article Liu, Xiaoran ; Cao, Yanwei ; Pal, B. ; ... - Physical Review Materials

We report on the selective fabrication of high-quality Sr₂IrO₄ and SrIrO₃ epitaxial thin films from a single polycrystalline Sr2IrO4 target by pulsed laser deposition. Using a combination of x-ray diffraction and photoemission spectroscopy characterizations, we discover that within a relatively narrow range of substrate temperature, the oxygen partial pressure plays a critical role in the cation stoichiometric ratio of the films, and triggers the stabilization of different Ruddlesden-Popper (RP) phases. Resonant x-ray absorption spectroscopy measurements taken at the Ir L edge and the O K edge demonstrate the presence of strong spin-orbit coupling, and reveal the electronic and orbital structuresmore »« less

Iridate Li8IrO₆: An Antiferromagnetic Insulator

Journal Article Skaggs, Callista M. ; Siegfried, Peter E. ; Kang, Chang-Jong ; ... - Inorganic Chemistry

A polycrystalline iridate Li8IrO6 material was prepared via heating Li2O and IrO2 starting materials in a sealed quartz tube at 650 degrees C for 48 h. The structure was determined from Rietveld refinement of room-temperature powder neutron diffraction data. Li8IrO6 adopts the nonpolar space group R (3) over bar with Li atoms occupying the tetrahedral and octahedral sites, which is supported by the electron diffraction and solid-state Li-7 NMR. This results in a crystal structure consisting of LiO4 tetrahedral layers alternating with mixed IrO6 and LiO6 octahedral layers along the crystallographic c-axis. The +4 oxidation state of Ir4+ was confirmedmore »« less

Spin-orbit driven magnetic insulating state with J_eff=1/2 character in a 4d oxide

Journal Article Calder, S. ; Li, Ling ; Okamoto, Satoshi ; ... - Physical Review B

The unusual magnetic and electronic ground states of 5d iridates have been shown to be driven by intrinsically enhanced spin-orbit coupling (SOC). The influence of appreciable but reduced SOC in creating the manifested magnetic insulating states in 4d oxides is less clear, with one hurdle being the existence of such compounds. Here, we present experimental and theoretical results on Sr4RhO6 that reveal SOC dominated behavior. Neutron measurements show the octahedra are both spatially separated and locally ideal, making the electronic ground state susceptible to alterations by SOC. Magnetic ordering is observed with a similar structure to an analogous Jeff=12 Mottmore »« less

Air-Stable Direct Bandgap Perovskite Semiconductors: All-Inorganic Tin-Based Heteroleptic Halides A_x SnCl_yI_z (A = Cs, Rb)

Journal Article Li, Jiangwei ; Stoumpos, Constantinos C. ; Trimarchi, Giancarlo G. ; ... - Chemistry of Materials

Semiconducting halide perovskites are a group of materials with exciting photoelectronic properties. Compared to the widely studied hybrid organic–inorganic perovskites, the all-inorganic derivatives are less well understood even as they promise high inherent stability. At the moment, such materials are limited due to the fact that there is a very narrow choice of inorganic cations that can stabilize the desirable perovskite structure. Herein we report on the synthesis and characterization of novel all-inorganic tin-based perovskites and perovskitoids that can be stabilized by the heteroleptic coordination of chloride and iodide anions, Cs₂SnCl₂I₂ (1) and Cs_2.38Rb_1.62Sn₃Cl₈I₂ (2), consist of two-dimensional (2D) layersmore »« less

Novel spin-orbit coupling driven emergent states in iridate-based heterostructures

Journal Article Hao, Lin ; Meyers, D. ; Dean, M. P. M. ; ... - Journal of Physics and Chemistry of Solids

Recent years have seen many examples of how the strong spin-orbit coupling present in iridates can stabilize new emergent states that are difficult or impossible to realize in more conventional materials. In this review we outline a representative set of studies detailing how heterostructures based on Ruddlesden-Popper (RP) iridates can be used to access yet more novel physics. Beginning with a short synopsis of iridate thin film growth, the effects of the heterostructure morphology on the RP iridates including Sr₂IrO₄ and SrIrO₃ are discussed. Example studies explore the effects of epitaxial strain, laser-excitation to access transient states, topological semimetallicity inmore »« less
