Recent high-resolution neutron inelastic scattering studies of magnetic systems (invited)
The advent of highly efficient (neutron) cold sources in research reactors has permitted studies of the excitations in condensed matter with improved instrumental resolution and at much lower energies than previously possible. For example, the triple-axis crystal spectrometer on the ILL cold source permits studies with resolutions in the range from (roughly) 1 to 0.02 meV (20 ..mu..eV). Even better resolution, extending below 1 ..mu..eV, is provided by the neutron-spin-echo spectrometer. In this article, recent work on magnetic systems, at ILL, using high-resolution inelastic scattering techniques, is briefly reviewed. We shall describe a spin-echo investigation of the critical dynamics of iron and then a series of triple-axis measurements of critical scattering and magnetic excitations in a variety of materials, USb, Rb/sub 2/CrCl/sub 4/, Pr, Nd, TMMC, CsCoCl/sub 3/, and, finally, a polarized neutron study of CsNiF/sub 3/.
