Magnetic structure, excitations and short-range order in honeycomb NaNiTeO.

NaNiTeOhas a layered hexagonal structure with a honeycomb lattice constituted by Niand a chiral charge distribution of Nathat resides between the Ni layers. In the present work, the antiferromagnetic (AFM) transition temperature of NaNiTeOis confirmed at≈ 27 K, and further, it is found to be robust up to 8 T magnetic field and 1.2 GPa external pressure; and, without any frequency-dependence.
