    • Abstract

       

      Three kinds of neutron scattering experiments have been performed to clarify the role of magnetic clusters on the various properties of re-entrant spin-glasses. The presence of two kinds of spin-wave excitations, the limitations of magnetic phase diagrams and the mechanism of slow dynamics have been discussed based on the results of inelastic scattering, diffuse scattering and time-resolved small-angle scattering experiments, respectively.
