Abstract
Neutron spin echo spectroscopy was used to investigate the dynamics of the disordered frustrated magnetic system CdCr1.8In0.2S4. This dynamics can be described as the sum of two exponential relaxation processes. While the fas t one does not depend on the temperature down to 25 K, the slow relaxation evidences a continuous slowing down on decreasing the temperature. (C) 1999 Published by Elsevier Science B.V.
