Title: Spin-orbit coupling controlled ground states in the double perovskite iridates $$\textit{A}_2\textit{B}$$IrO$$_6$$ ($$\textit{A}$$ = Ba, Sr; $$\textit{B}$$ = Lu, Sc)

Abstract

Iridates with the 5$d^4$ electronic configuration have attracted recent interest due to reports of magnetically ordered ground states despite longstanding expectations that their strong spin-orbit coupling would generate a $$\textit{J}$$ = 0 electronic ground state for each Ir⁵⁺ ion. The major focus of prior research has been on the double perovskite iridates Ba₂YIrO₆ and Sr₂YIrO₆, where the nature of the ground states (i.e., ordered vs nonmagnetic) is still controversial. Here, we present neutron powder diffraction, high-energy-resolution fluorescence-detected x-ray absorption spectroscopy (HERFD-XAS), resonant inelastic x-ray scattering (RIXS), magnetic susceptibility, and muon spin relaxation data on the related double perovskite iridates Ba₂LuIrO₆, Sr₂LuIrO₆, Ba₂ScIrO₆, and Sr₂ScIrO₆ that enable us to gain a general understanding of the electronic and magnetic properties for this family of materials. In this work, our HERFD-XAS and RIXS measurements establish $$\textit{J}$$ = 0 electronic ground states for the Ir⁵⁺ ions in all cases, with similar values for Hund's coupling $$J_H$$ and the spin-orbit coupling constant $$λ_{\text{SOC}}$$. Our bulk susceptibility and muon spin relaxation data find no evidence for long-range magnetic order or spin freezing, but they do exhibit weak magnetic signals that are consistent with extrinsic local moments. Our results indicate that the large $$λ_{\text{SOC}}$$ is the key driving force behind the electronic and magnetic ground states realized in the $5d^4$ double perovskite iridates, which agrees well with conventional wisdom.

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

Identifying $$\textit{f}$$-electron symmetries of UTe₂ with O-edge resonant inelastic x-ray scattering

Journal Article Liu, Shouzheng ; Xu, Yishuai ; Kotta, Erica C. ; ... - Physical Review. B

The recent discovery of spin-triplet superconductivity emerging from a nonmagnetic parent state in UTe₂ has stimulated great interest in the underlying mechanism of Cooper pairing. Experimental characterization of short-range electronic and magnetic correlations is vital to understanding these phenomena. Here we use resonant inelastic x-ray scattering (RIXS), x-ray absorption spectroscopy (XAS), and atomic-multiplet-based modeling to shed light on the active debate betweenmore »« less

Revisiting the Kitaev material candidacy of ${Ir}^{4 +}$ double perovskite iridates

Journal Article Aczel, Adam A. ; Clancy, James P. ; Chen, Qiang ; ... - Physical Review B

Quantum magnets with significant bond-directional Ising interactions, so-called Kitaev materials, have attracted tremendous attention recently in the search for exotic spin liquid states. Here we present a comprehensive set of measurements that enables us to investigate the crystal structures, Ir⁴⁺ single-ion properties, and magnetic ground states of the double perovskite iridates La₂BIrO₆ (B = Mg, Zn) and A₂CeIrO₆ (A = Ba, Sr) with a large nearest-neighbor distance >5 angstrom between Ir⁴⁺ ions. Our neutron powder diffraction data on Ba₂CeIrO₆ can be refined in the cubic space group Fmmore »« less

The Impact of Structural Distortions on the Magnetism of Double Perovskites Containing 5d¹ Transition-Metal Ions

Journal Article da Cruz Pinha Barbosa, Victor ; Xiong, Jie ; Tran, Phuong Minh ; ... - Chemistry of Materials

Five double perovskites, each containing a transition-metal ion with a 5d¹ configuration, have been studied to better understand the surprising diversity of magnetic ground states seen in these isoelectronic compounds. Ba₂ZnReO₆ adopts the cubic double perovskite structure and magnetically orders below 16 K, with a canted ferromagnetic structure and a saturated magnetization of ~0.24 μ_B/Re. X-ray magnetic circular dichroism indicates a substantial orbital moment of approximately 0.4 μ_B/Re that opposes the spin moment. The structures of Ba₂NaOsO₆ (canted ferromagnet, T_C = 7 K) and Ba₂LiOsO₆ (antiferromagnet, T_N = 8 K) are reinvestigated using time-of-flight neutron powder diffraction and found tomore »« less
