Title: Impact of Sn substitution on the structure and magnetism of ${Sr}_{2} {IrO}_{4}$

Abstract

Here, the magnetic behavior of Sn-substituted Sr₂IrO₄ has been examined through magnetization measurements and single-crystal neutron diffraction on Sr₂Ir_1-xSn_xO₄ for 0.05≲x≲0.35. For all x examined, the magnetic ground state is similar to that induced in Sr₂IrO₄ by application of a magnetic field. This magnetic state is characterized by a small net moment due to the alignment of canted moments within an otherwise antiferromagnetic structure. The weak ferromagnetic behavior is observed in the magnetization data for both unique crystallographic orientations. Diffraction data reveal an anisotropic response in the lattice parameters, with an overall lattice expansion, as well as a small reduction in the rotation of the IrO₆ octahedra. Lastly, the magnetic ordering temperature is continually suppressed with increasing x, and long-range magnetic order persists to the highest Sn concentrations synthesized.

Electrical Control of Structural and Physical Properties via Strong Spin-Orbit Interactions in ${Sr}_{2} {IrO}_{4}$

Journal Article Cao, Gang ; Terzic, J. ; Zhao, H. D. ; ... - Physical Review Letters

Electrical control of structural and physical properties is a long-sought, but elusive goal of contemporary science and technology. We propose that a combination of strong spin-orbit interactions (SOI) and a canted antiferromagnetic Mott state is sufficient to attain that goal. The antiferromagnetic insulator Sr₂IrO₄ provides a model system in which strong SOI lock canted Ir magnetic moments to IrO6 octahedra, causing them to rigidly rotate together. A novel coupling between an applied electrical current and the canting angle reduces the N´eel temperature and drives a large, nonlinear lattice expansion that closely tracks the magnetization, increases the electron mobility, and precipitatesmore »« less

Pseudospin-lattice coupling in the spin-orbit Mott insulator ${Sr}_{2} {IrO}_{4}$

Journal Article Porras, J. ; Bertinshaw, J. ; Liu, H. ; ... - Physical Review B

Spin-orbit entangled magnetic dipoles, often referred to as pseudospins, provide a new avenue to explore novel magnetism inconceivable in the weak spin-orbit coupling limit, but the nature of their low-energy interactions remains to be understood. In this paper, we present a comprehensive study of the static magnetism and low-energy pseudospin dynamics in the archetypal spin-orbit Mott insulator Sr₂IrO₄. We find that in order to understand even basic magnetization measurements, a formerly overlooked in-plane anisotropy is fundamental. In addition to magnetometry, we use neutron diffraction, inelastic neutron scattering, and resonant elastic and inelastic x-ray scattering to identify and quantify the interactionsmore »« less

Growth and electrical transport properties of ${La}_{0.7} {Sr}_{0.3} {MnO}_{3}$ thin films on ${Sr}_{2} {IrO}_{4}$ single crystals

Journal Article Moon, E. J. ; May, A. F. ; Shafer, P. ; ... - Physical Review B

We report the physical properties of La_0.7Sr_0.3MnO₃ thin films on Sr₂IrO₄ single crystals. The manganite films are deposited using oxide molecular beam epitaxy on flux-grown (001)-oriented iridate crystals. Temperature-dependent magnetotransport and x-ray magnetic circular dichroism measurements reveal the presence of a ferromagnetic metallic ground state in the films, consistent with films grown on SrTiO₃ and La_0.3Sr_0.7Al_0.65Ta_0.35O₃. A parallel resistance model is used to separate conduction effects within the Sr₂IrO₄ substrate and the La_0.7Sr_0.3MnO₃ thin films, revealing that the measured resistance maximum does not correspond to the manganite Curie temperature but results from a convolution of properties of the near-insulating substratemore »« less

Anisotropic antiferromagnetic order in the spin-orbit coupled trigonal-lattice ${Ca}_{2} {Sr}_{2} {IrO}_{6}$

Here, we used single-crystal x-ray and neutron diffraction to investigate the crystal and magnetic structures of trigonal lattice iridate Ca₂Sr₂IrO₆. The crystal structure is determined to be R¯3 with two distinct Ir sites. The system exhibits long-range antiferromagnetic order below T_N = 13.1 K. The magnetic wave vector is identified as (0,0.5,1) with ferromagnetic coupling along the a axis and antiferromagnetic correlation along the b axis. Spins align dominantly within the basal plane along the [1,2,0] direction and tilt 34° toward the c axis. The ordered moment is 0.66(3) μ_B/Ir, larger than other iridates where iridium ions form corner- ormore »« less

Hyperhoneycomb Iridate $β - {Li}_{2} {IrO}_{3}$ as a Platform for Kitaev Magnetism

Journal Article Takayama, T. ; Kato, A. ; Dinnebier, R. ; ... - Physical Review Letters

A complex iridium oxide β-Li₂IrO₃ crystallizes in a hyperhoneycomb structure, a three-dimensional analogue of honeycomb lattice, and is found to be a spin-orbital Mott insulator with J_eff = 1/2 moment. Ir ions are connected to the three neighboring Ir ions via Ir-O₂-Ir bonding planes, which very likely gives rise to bond-dependent ferromagnetic interactions between the J_eff = 1/2 moments, an essential ingredient of Kitaev model with a spin liquid ground state. Dominant ferromagnetic interaction between J(eff) = 1/2 moments is indeed confirmed by the temperature dependence of magnetic susceptibility chi(T) which shows a positive Curie-Weiss temperaturemore »« less
