Evolution of crystal field and intraionic interactions in the ilmenite $A$IrO$_3$ ($A$ = Mg, Zn, Cd) and hyperhoneycomb $\beta$-ZnIrO$_3$
Local multiplet parameters match in ilmenite and hyperhoneycomb ZnIrO3, showing lattice structure alone controls their distinct magnetic states.

Claims
The local multiplet parameters of ilmenite ZnIrO3 and hyperhoneycomb β-ZnIrO3 are found to be nearly identical, demonstrating that their different magnetic ground states are primarily governed by their distinct lattice structures rather than the single-ion properties.
The multiplet model used to fit the RIXS spectra fully captures the crystal-field and intraionic parameters without significant unaccounted contributions from covalency, phonons, or other many-body effects that could alter the extracted values.
RIXS multiplet analysis finds increasing trigonal distortion with larger A-site ions in AIrO3 iridates, explaining J=1/2 deviations in CdIrO3, while ilmenite and hyperhoneycomb ZnIrO3 have matching local parameters so their magnetic differences arise from lattice connectivity.
