Title: Evolution of competing magnetic order in the J_eff=1/2 insulating state of Sr₂Ir_1-xRu_xO₄

Abstract

We investigate the magnetic properties of the series Sr₂Ir_1-xRu_xO₄ with neutron, resonant x-ray and magnetization measurements. The results indicate an evolution and coexistence of magnetic structures via a spin flop transition from ab-plane to c-axis collinear order as the 5d Ir4⁺ ions are replaced with an increasing concentration of 4d Ru4⁺ ions. The magnetic structures within the ordered regime of the phase diagram (x<0.3) are reported. Despite the changes in magnetic structure no alteration of the J_eff=1/2 ground state is observed. This behavior of Sr₂Ir_1-xRu_xO₄ is consistent with electronic phase separation and diverges from a standard scenario of hole doping. The role of lattice alterations with doping on the magnetic and insulating behavior is considered. Our results presented here provide insight into the magnetic insulating states in strong spin-orbit coupled materials and the role perturbations play in altering the behavior.

Spin-orbit tuned metal-insulator transitions in single-crystal Sr₂Ir_1–xRh_xO₄ (0≤x≤1)

Journal Article Qi, T. F. ; Korneta, O. B. ; Li, L. ; ... - Physical Review. B, Condensed Matter and Materials Physics

Sr₂IrO₄ is a magnetic insulator driven by spin-orbit interaction (SOI) whereas the isoelectronic and isostructural Sr₂RhO₄ is a paramagnetic metal. The contrasting ground states have been shown to result from the critical role of the strong SOI in the iridate. Our investigation of structural, transport, magnetic, and thermal properties reveals that substituting 4d Rh⁴⁺ (4d⁵) ions for 5d Ir⁴⁺ (5d⁵) ions in Sr₂IrO₄ directly reduces the SOI and rebalances the competing energies so profoundly that it generates a rich phase diagram for Sr₂Ir_1–xRh_xO₄ featuring two major effects: (1) Light Rh doping (0 ≤ x ≤ 0.16) prompts a simultaneous andmore »« less

Hexagonal BaIrO₃ is a magnetic insulator driven by the spin-orbit interaction (SOI), whereas BaRuO₃ is an enhanced paramagnetic metal. Here, our investigation of structural, magnetic, transport, and thermal properties reveals that substitution of Ru⁴⁺ (4d⁴) ions for Ir⁴⁺ (5d⁵) ions in BaIrO₃ reduces the magnitudes of the SOI and a monoclinic structural distortion and rebalances the competition between the SOI and the lattice degrees of freedom to render an evolution from a magnetic insulting state to a robust metallic state. The central findings of this paper are as follows: (1) light Ru doping (0 < x ≤ 0.15) prompts simultaneous,more »« less

Strong anisotropy within a Heisenberg model in the $J_{eff} = \frac{1}{2}$ insulating state of ${Sr}_{2} {Ir}_{0.8} {Ru}_{0.2} O_{4}$

Journal Article Calder, Stuart A. ; Kim, J. W. ; Taylor, Alice E. ; ... - Physical Review B

The dispersive magnetic excitations in Sr2IrO4 have previously been well described within an isospin-1/2 Heisenberg model on a square lattice that revealed parallels with La2CuO4. Here we investigate the inelastic spectra of Sr2Ir0.8Ru0.2O4 with resonant inelastic x-ray scattering (RIXS) at the Ir L3 edge. The results are well described using linear spin-wave theory within a similar Heisenberg model applicable to Sr2IrO4; however, the disorder induced by the substitution of 20%Ir4+ ions for Ru4+ removes longer range exchange interactions. A large spin gap (40 meV) is measured indicating strong anisotropy from spin-orbit coupling that is manifest due to the altered magneticmore »« less

Effect of electron correlation in Sr(Ca)Ru{sub 1-x}Cr{sub x}O{sub 3}: Density functional calculation

Journal Article Hadipour, H ; Akhavan, M - Journal of Solid State Chemistry

We have investigated the electronic structure of Sr(Ca)Ru{sub 1-x}Cr{sub x}O{sub 3} using the full potential linearized augmented plane wave method by different approximation such as LSDA and LSDA+U. The LSDA calculation suggest that Cr{sup 4+}-Ru{sup 4+} hybridization is responsible for the high Curie temperature T{sub C} in SrRu{sub 1-x}Cr{sub x}O{sub 3}, but it cannot completely describe its physical behavior. Our LSDA+U DOS results for SrRu{sub 1-x}Cr{sub x}O{sub 3} clearly establishes renormalization of the intra-atomic exchange strength at the Ru sites, arising from the Cr-Ru hybridization. The antiferromagnetic coupling of Cr{sup 3+} with Ru{sup 4+,5+} lattice increases the screening, which ismore »« less

Evolution of magnetism in single-crystal $C a_{2} R u_{1 - x} I r_{x} O_{4} (0 \leq x \leq 0.65)$

Journal Article Yuan, S. J. ; Terzic, J. ; Wang, J. C. ; ... - Physical Review. B, Condensed Matter and Materials Physics

In this paper, we report structural, magnetic, transport, and thermal properties of single-crystal Ca₂Ru_1-xIr_xO₄(0≤x≤0.65). Ca₂RuO₄ is a structurally driven Mott insulator with a metal-insulator transition at T_MI=357K, which is well separated from antiferromagnetic order at T_N=110K. Substitution of a 5d element, Ir, for Ru enhances spin-orbit coupling and locking between the structural distortions and magnetic moment canting. Ir doping intensifies the distortion or rotation of Ru/IrO₆ octahedra and induces weak ferromagnetic behavior along the c axis. In particular, Ir doping suppresses T_N but concurrently causes an additional magnetic ordering T_N2 at a higher temperature up to 210 K for x=0.65.more »« less
