Abstract

We examine the magnetic excitation spectrum in the S=2 Heisenberg antiferromagnet CrCl₂. Inelastic neutron scattering measurements on powder samples are able to determine the significant exchange interactions in this system. A large anisotropy gap is observed in the spectrum below the Néel temperature and the ratio of the two largest exchange constants is J_c/J_b=9.1±2.2. However, no sign of a gapped quantum spin liquid excitation was found in the paramagnetic phase.
