Spin-lattice and electron-phonon coupling in 3 $d$ /5 $d$ hybrid Sr $_{3}$ NiIrO $_{6}$

Kenneth R. O'Neal, Arpita Paul, Amal al-Wahish +10

While 3 $d$ -containing materials display strong electron correlations, narrow band widths, and robust magnetism, 5 $d$ systems are recognized for strong spin-orbit coupling, increase…

Spin dynamics and field-induced magnetic phase transition in the honeycomb Kitaev magnet $α$ -Li $_{2}$ IrO $_{3}$

Sungkyun Choi, S. Manni, J. Singleton +7

The layered honeycomb iridate $α$ -Li $_{2}$ IrO $_{3}$ displays an incommensurate magnetic structure with counterrotating moments on nearest-neighbor sites, proposed to be stabilized by s…

Evidence for $J_{eff} = 0$ ground state and defect-induced spin glass behaviour in the pyrochlore osmate Y $_{2}$ Os $_{2}$ O $_{7}$

N. R. Davies, C. V. Topping, H. Jacobsen +14

We present AC and DC magnetometry, heat capacity, muon spin relaxation ( $μ$ SR) and resonant inelastic X-ray scattering (RIXS) studies of the pyrochlore osmate Y $_{2}$ Os $_{2}$ O $_{7}$ . We…

Control of the third dimension in copper-based square-lattice antiferromagnets

Paul A. Goddard, John Singleton, Isabel Franke +20

Using a mixed-ligand synthetic scheme, we create a family of quasi-two-dimensional antiferromagnets, namely, [Cu(HF $_{2}$ )(pyz) $_{2}$ ]ClO $_{4}$ [pyz = pyrazine], [Cu $L_{2}$ (pyz) $_{2}$ ](ClO$_…
