Magnetic van der Waals material NiPS₃. a Crystal structure of NiPS₃. Red arrows indicate the spin orientations of Ni atoms below Néel temperature (T_N). b Atomic force microscope image and thickness line profile of monolayer NiPS₃. Optical image of the sample is shown in inset. The black and white scale bars are 1 and 5 µm, respectively
