Seeking higher-order modulation peaks of Na3Co2SbO6

The Kitaev honeycomb model has garnered significant interest due to its exactly solvable quantum spin liquid (QSL) ground state. Essentially all the candidate materials exhibit long-range magnetic orders at low temperatures due to non-Kitaev (e.g., Heisenberg) interactions. While conventional wisdom has rendered single-q zigzag order to be the most common ground state, recent investigations on cobaltates Na3Co2SbO6 (NCSO) has uncovered evidence for multi-q order. Here we propose to seek higher-order modulation peaks in NCSO on WISH, which is serving as a direct smoking-gun evidence of multi-q order. The rich field-induced phases in NCSO provides a great opportunity to find such peaks.
