The magnetic structure of VPS3
The family of compounds MPS3 (M = transition metal) are examples of quasi-two dimensional materials. The transition metal atoms lie on a honeycomb lattice in the ab planes, and the planes are weakly bound by van-der-Waals forces. One compound that has received little attention is VPS3. It has the smallest electronic band gap of the family, making metallization under pressure more achievable; a study we recently carried out. The compound is not fully stoichiometric when synthesized and is deficient in vanadium. The magnetism of the compound is potentially interesting as theory suggests a honeycomb lattice of S = 3/2 moments might dimerize to form a Peierls-like structure. The compound also makes an interesting contrast with its sister antiferromagnets CoPS3 and NiPS3, with the same crystal structure and spins S=3/2 and S=1. We propose to study the magnetic properties of V0.9PS3 as an example of low-dimensional model magnetism, and the role of charge and vacancy disorder on the magnetic properties. We require neutron scattering to determine the magnetic structure. Test measurements have suggested this structure to be an interesting contrast to the rest of the MPS3 family.
