Ultrasonic Resonance and Relaxation in RbCl:OH
نویسندگان
چکیده
The change of elastic constants and mechanical loss from [loo] elastic dipoles are calculated on the basis of a six level tunneling model. Resonance and relaxation mechanisms are treated together, and expressions for Cfand C11sound modes are given. The results are used to analyse experimental data for the RbC1:OH system. The low temperature ultrasonic attenuation is attributed to the resonance mechanism, and the frequency and the concentration dependence are interpreted in terms of dynamical and static interaction between dipoles.

Resonance Ultrasonic Spectroscopy of a Nanofibrous Composite and Studying the Effect of Surface/Interface
Resonances are intrinsic characteristics of an elastic object, which are completely independent of the source of excitation. The appropriate utilization of the information contained within the resonance spectra and the identification of the resonance frequencies of the object can be used as a potent tool for material characterization. In this paper, a new mathematical model for the wave diffrac...
متن کاملInfluence of Plastic Deformation on the Temperature Dependence of Ultrasonic Attenuation in Copper Single Crystals
The influence of plastic deformation (O<&<10%) on the MHz-ultrasonic attenuation a in single crystals of pure Cu, Cu50ppmAu and Cul30ppmAu has been measured over the temperature range 4<T<300K. The major contributions to the total attenuation originate from dislocation resonance, double-kink relaxation, phonon-electron interaction (at T<50K) and non-dislocation effects which are discussed espec...
