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

Abstract

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 precipitates a unique resistive switching effect. Our studies open new avenues for understanding fundamental physics driven by strong SOI in condensed matter, and provide a new paradigm for functional materials and devices.

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

Magnetic order, disorder, and excitations under pressure in the Mott insulator ${Sr}_{2} {IrO}_{4}$

Journal Article Li, Xiang ; Cooper, S. E. ; Krishnadas, A. ; ... - Physical Review B

Protected by the interplay of on-site Coulomb interactions and spin-orbit coupling, Sr₂IrO₄ at high pressure is a rare example of a Mott insulator with a paramagnetic ground state. Here, using optical Raman scattering, we measure both the phonon and magnon evolution in Sr₂IrO₄ under pressure and identify three different magnetically-ordered phases, culminating in a spin-disordered state beyond 18 GPa. A strong first-order structural phase transition drives the magnetic evolution at ~10 GPa with reduced structural anisotropy in the IrO₆ cages, leading to increasingly isotropic exchange interactions between the Heisenberg spins and a spin-flip transition to c-axis-aligned antiferromagnetic order.

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

Correlation between antiferromagnetic and Mott states in spin orbit coupled ${Sr}_{2} Ir O_{4}$ : A study of ${Sr}_{2} {Ir}_{1 - x} M_{x} O_{4}$ ( $M = Fe$ or Co)

Journal Article Hu, Bing ; Zhao, Hengdi ; Zhang, Yu ; ... - Physical Review B

Sr₂IrO₄ is an archetypal spin-orbit-coupled Mott insulator with an antiferromagnetic state below 240 K. Here we report results of our study on single crystals of Sr₂Ir_1–xFe_xO₄ (0 ≤ x < 0.32) and Sr₂Ir_1–xCo_xO₄ (0 ≤ x < 0.22). Fe doping retains the antiferromagnetic state but simultaneously precipitates an emergent metallic state whereas Co doping causes a rapid collapse of both the antiferromagnetic and Mott states, giving rise to a confined metallic state featuring a pronounced linearity of the basal-plane resistivity up to 700 K. The results indicate tetravalent Fe⁴⁺ (3d⁴) ions in the intermediate spin state with S = 1more »« less

Evidence for a low-temperature magnetic ground state in double-perovskite iridates with $I r^{5 +} (5 d^{4})$ ions

Journal Article Terzic, Jasminka ; Zheng, Hao ; Ye, Feng ; ... - Physical Review B

Here, we report an unusual magnetic ground state in single-crystal, double-perovskite Ba₂YIrO₆ and Sr-doped Ba₂YIrO₆ with Ir⁵⁺ (5d⁴) ions. Long-range magnetic order below 1.7 K is confirmed by dc magnetization, ac magnetic susceptibility, and heat-capacity measurements. The observed magnetic order is extraordinarily delicate and cannot be explained in terms of either a low-spin S=1 state, or a singlet J_eff=0 state imposed by the spin-orbit interactions (SOI). Alternatively, the magnetic ground state appears consistent with a SOI that competes with comparable Hund's rule coupling and inherently large electron hopping, which cannot stabilize the singlet J_eff=0 ground state. However, this picture ismore »« less
