Title: Single-Laser-Pulse-Driven Thermal Limit of the Quasi-Two-Dimensional Magnetic Ordering in ${Sr}_{2} {IrO}_{4}$

Abstract

Upon femtosecond-laser stimulation, generally materials are expected to recover back to their thermal- equilibrium conditions, with only a few exceptions reported. Here, we demonstrate that deviation from the thermal-equilibrium pathway can be induced in canonical 3D antiferromagnetically (AFM) ordered Sr₂IrO₄ by a single 100-fs-laser pulse, appearing as losing long-range magnetic correlation along one direction into a glassy condition. We further discover a "critical-threshold ordering"behavior for fluence above approximately 12 mJ/cm², which we show corresponds to the smallest thermodynamically stable c-axis correlation length needed to maintain long-range quasi-two-dimensional AFM order. We suggest that this behavior arises from the crystalline anisotropy of the magnetic-exchange parameters in Sr₂IrO₄, whose strengths are associated with distinctly different timescales. As a result, they play out very differently in the ultrafast recovery processes, compared with the thermal-equilibrium evolution. Thus, our observations are expected to be relevant to a wide range of problems in the nonequilibrium behavior of low-dimensional magnets and other related ordering phenomena.

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

Journal Article Sheng, Jieming ; Ye, Feng ; Hoffmann, Christina ; ... - Physical Review B

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

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

Journal Article May, Andrew F. ; Cao, Huibo ; Calder, Stuart A. - Physical Review Materials

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 reductionmore »« less

Persistent Paramagnons Deep in the Metallic Phase of ${Sr}_{2 - x} {La}_{x} {IrO}_{4}$

Journal Article Gretarsson, H. ; Sung, N. H. ; Porras, J. ; ... - Physical Review Letters

We have studied the magnetic excitations of electron-doped Sr_2-xLa_xIrO₄ (0 ≤ x ≤ 0.10) using resonant inelastic x-ray scattering at the Ir L₃ edge. The long-range magnetic order is rapidly lost with increasing x, but two-dimensional short-range order (SRO) and dispersive magnon excitations with nearly undiminished spectral weight persist well into the metallic part of the phase diagram. The magnons in the SRO phase are heavily damped and exhibit anisotropic softening. Their dispersions are well described by a pseudospin-1=2 Heisenberg model with exchange interactions whose spatial range increases with doping. We also find a doping-independent high-energy magnetic continuum, which ismore »« less

Dynamic Spin Correlations in the Honeycomb Lattice ${Na}_{2} {IrO}_{3}$ Measured by Resonant Inelastic x-Ray Scattering

Journal Article Kim, Jungho ; Chaloupka, Jiří ; Singh, Yogesh ; ... - Physical Review. X

Kitaev quantum spin liquid is a prime example of novel quantum magnetism of spin-orbit entangled pseudospin-1/2 moments in a honeycomb lattice. Most candidate materials such as Na₂IrO₃ have many competing exchange interactions beyond the minimal Kitaev-Heisenberg model whose small variations in the strength of the interactions produce huge differences in low energy dynamics. An incomplete knowledge of dynamic spin correlations hampers identification of a minimal model and quantification of the proximity to the Kitaev quantum spin-liquid phase. Here, we report fully momentum- and energy-resolved magnetic excitation spectra in a honeycomb lattice Na₂IrO₃ measured using resonant inelastic x-ray scattering. The state-of-the-artmore »« less

Coexistence of static and dynamic magnetism in the Kitaev spin liquid material ${Cu}_{2} {IrO}_{3}$

Journal Article Kenney, Eric M. ; Segre, Carlo U. ; Lafargue-Dit-Hauret, William ; ... - Physical Review B

Searching for a Kitaev spin liquid phase motivated intense research on the honeycomb iridate materials. However, access to a spin liquid ground state has been hindered by magnetic ordering. Cu₂IrO₃ is a new honeycomb iridate without thermodynamic signatures of a long-range order. Here, we use muon spin relaxation to uncover the magnetic ground state of Cu₂IrO₃. We find a two-component depolarization with slow- and fast-relaxation rates corresponding to distinct regions with dynamic and static magnetism coexisting in the material. X-ray absorption spectroscopy and first-principles calculations identify a mixed copper valence as the origin of this behavior. Furthermore, our results suggestmore »« less
