The magnetic density of states in NiPS3
NiPS3 belongs to a family of quasi-2D antiferromagnets on a honeycomb lattice. We have previously used neutron spectroscopy to establish that other members of the family are very good model magnets, namely: MnPS3, which is Heisenberg-like; and FePS3, which is Ising-like. NiPS3 shows novel effects in comparison, and we now wish to measure the magnetic density of states from a powder using time-of-flight spectroscopy. We already have data from a thermal three-axis spectrometer that shows a potential feature at ~6.5 meV and need a combination of IN4 and D7 to verify that this mode is indeed magnetic, and to search for magnetic features at larger energy transfers.
