« Glassy » and plastic crystals of cyanoadamantane : a Brillouin scattering investigation
The elastic constants of cyanoadamantane have been measured in the plastic and «glassy» crystal phases. A special attention has been given to the temperature evolution of C 11 as well as to the damping of the corresponding mode. Comparison with neutron results shows a strong dispersion at room temperature. The temperature dependence of C 11 in the plastic phase has been explained by the setting-up of a local antiferro ordering of molecules Determination des constantes d'elasticite d'apres les mesures de diffusion Brillouin sur monocristal entre 80 et 435 K. Variation thermique de C 11 et attenuation du mode correspondant. Comparaison aux donnees de diffusion de neutrons: existence d'une forte dispersion a temperature ambiante. Explication de la variation thermique de C 11 en phase plastique par apparition d'un ordre moleculaire local de type antiferro
