Magnetic structure of the quasi-two-dimensional antiferromagnetNiPS3

Using various macroscopic and microscopic techniques, including magnetometry and neutron and x-ray diffraction measurements, the authors investigate the magnetic properties of the quasi-two-dimensional antiferromagnet NiPS${}_{3}$. Contrary to previous measurements, the authors find that the material orders antiferromagnetically with a propagation vector of $\mathbf{k}$=[010]. This clarification of the magnetic structure is hoped to lead to a better understanding of the overall dynamics in these types of systems.
