Abstract
The magnetic properties and magnetic structure are presented for CoPS3, a quasi-twodimensional antiferromagnet on a honeycomb lattice with a Néel temperature of TN ∼ 120 K. The compound is shown to have XY-like anisotropy in its susceptibility, and the anisotropy is analysed to extract crystal field parameters. For temperatures between 2K and 300K, no phase transitions were observed in the field-dependent magnetization up to 10 Tesla. Singlecrystal neutron diffraction shows that the magnetic propagation vector is k = (010) with the moments mostly along the a axis and with a small component along the c axis, which largely verifies the previously-published magnetic structure for this compound. The magnetic Bragg peak intensity decreases with increasing temperature as a power law with exponent 2β = 0.60 ± 0.01 for T > 0.9 TN.
