Title: Magnetism of ${Ir}^{5 +}$ -based double perovskites: Unraveling its nature and the influence of structure

Abstract

A combination of x-ray-diffraction, x-ray absorption, x-ray magnetic circular dichroism, macroscopic magnetization, and muon-spin relaxation measurements is used to investigate the interplay between structure (both crystallography and microstructure) and magnetism in Sr₂ YIrO₆ as a function of both chemical (Ca-doping) and physical (hydrostatic) pressure. X-ray absorption spectroscopy clearly shows that the physical pressure is more effective in modifying the structure. On the other hand, the dichroic measurements evidence a constant magnetic signal with physical pressure and strong differences with Ca-doping. Muon-spin relaxation reveals the presence of magnetic order, even when this is hidden in the magnetization data. From the combined analysis, the magnetic results are explained in terms of the presence of Ir⁶⁺ or Ir⁴⁺ ions in magnetic clusters, most likely located at and triggered by antisite disorder. The measurements under high physical pressure indicate that the magnetic state is independent of the crystallographic details such as Ir-O distances and Ir-O-Y angles.

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

Magnetism out of antisite disorder in the $J = 0$ compound ${Ba}_{2} {YIrO}_{6}$

Journal Article Chen, Qiang ; Svoboda, Chris ; Zheng, Qiang ; ... - Physical Review B

Here, we systematically investigate the magnetic properties and local structure of Ba₂YIrO₆ to demonstrate that Y and Ir lattice defects in the form of antiphase boundary or clusters of antisite disorder affect the magnetism observed in this 5d⁴ compound. The experimental investigation involved comparison of the magnetic properties and atomic imaging of (1) a slow-cooled crystal, (2) a crystal quenched from 900°C after growth, and (3) a crystal grown using a faster cooling rate during growth than the slow-cooled one. Atomic-scale imaging by scanning transmission electron microscopy (STEM) shows that quenching from 900°C introduces Ir-rich antiphase boundaries in the crystals,more »« less

The magnetic structure and metal-insulator transition in antiferromagnetic (AFM) BaMn₂As₂ and Ba_1-xK_xMn₂As₂ single crystals have been investigated by ⁵⁵Mn and ⁷⁵As nuclear magnetic resonance (NMR) measurements. In the parent AFM insulator BaMn₂As₂ with a Néel temperature TN=625 K, we observed a ⁵⁵Mn zero-field NMR (ZFNMR) spectrum and confirmed the G-type AFM structure from the field dependence of the ⁵⁵Mn spectra and ⁷⁵As NMR spectra below TN. In hole-doped crystals with x>0.01, similar ⁵⁵Mn ZFNMR spectra were observed and the AFM state was revealed to be robust up to x=0.4 with the ordered moment nearly independent of x.

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
