ULTRASONIC STUDY OF THE CUBIC-TETRAGONAL PHASE CHANGE AND THE CURIE TEMPERATURE OF SINGLE CRYSTAL SRTI03
Abstract
The acoustic attenuation and velocity in single crystal strontium titanate were studied over the temperature range 4-300 K at frequencies from 10-150 mc. The velocity data are in essential AGREEMENT WITH PREVIOUSLY REPORTED RESULTS. The attenuation exhibits two dominant maxima, one at 110 K attributed to a cubic-tetragonal phase transformation, and the second at 50 K attributed to dielectric losses below the ferroelectric curie point. The 110 K maximum is discussed macroscopically in t rms of a scattering model. Results of x-ray and Mossbauer experiments are inclu ed. Automatic equipment for direct recording of attenuation data is described. (Author)
