Two-step freezing process in the mixed crystal RADP
Abstract
Two, significantly different, temperatures are found to be related to the freezing process in the mixed crystal Rb0.38(ND4)0.62D2PO4. This observation - based on neutron, Brillouin, and dielectrin methods - indicates a temperature region of enhanced spatial heterogeneity in the relaxational dynamics of the system. A molecular dynamics simulation supports this interpretation. © 1991.
