Abstract
Abstract Uniform high pressure experiments up to 5 kbar on quasi one-dimensional singlet ground state and the induced magnetic moment systems AFeX3 are reported. The pressure-induced changes in the magnetic ordering vector are related to induced structural phase transitions. The anisotropic compression of the lattice may give rise to induced moment formation in the CsFeX3 compounds. Inelastic neutron scattering experiments show that the anisotropic compression effect on the magnetic excitations is not visible. However, structural changes show a marked effect on the magnetic excitation spectrum. Predictions are made for the magnetic excitation spectra of the induced moment systems RbFeCl3 and TIFeCl3.
