Abstract
NiPS${}_{3}$ is a layered van der Waals compound. Like graphite, it can be delaminated down to a monolayer. Unlike graphite, it is magnetic. Neutron inelastic scattering has been performed on bulk single-crystal samples of NiPS${}_{3}$ to measure the magnetic dynamics, key to understanding the magnetic properties. Clear spin waves are observed, quantifying the magnetic exchange within and between the layers and the predominantly planar anisotropy. The findings have important ramifications for NiPS${}_{3}$ in graphene-based research.
