Exploring the ground state of two-dimensional (2D) magnetic systems enriches the fundamental understanding of magnetism and boosts the applications. The authors here show the suppression of magnetic order and 2D XY behavior in XXZ-type antiferromagnet NiPS3 when approaching the monolayer limit by Raman spectroscopy.
