Spin-waves in 2D honeycomb lattice $XXZ$-type van der Waals antiferromagnet CoPS${}_3$

Chaebin Kim, Jaehong Jeong, Takatsugu Masuda +5

The magnetic excitations in CoPS${}_3$, a two-dimensional van der Waals (vdW) antiferromagnet with spin $S=3/2$ on a honeycomb lattice, has been measured using powder inelastic neutr…
