We report magnetization and Raman spectroscopy study on single crystals of VOC1,a van der Waals antiferromag-netic material.Magnetization measurement confirms an antiferromagnetic transition at 79 K and a magnetic easy axis along crystallographic a direction.The temperature-dependent Raman spectrum reveals five peaks at 30 K.Below the Neel tem-perature TN,the Raman-active modes 247 cm-1 and 404 cm-1 remarkably deviate from the standard Boltzmann function,which is ascribed to the strong magnetoelastic coupling between spins and phonons.We further observe an anomaly in 383 cm-1 mode at around 150 K.This coincides with the broad maximum in VOCl\'s magnetic susceptibility,suggesting a development of short-ranged magnetic order at this temperature.
