Abstract

The development of a new ultrasonic sing around system has been described. The equipment has been used to investigate the behaviour of the second order eleastic moduli of single crystal specimens of Gadolinium, Terbium, Dysprosium and Erbium under conditions of varying temperature, pressure and magnetic field .
From the results, some indication of the performance of the new system has been obtained. The behaviour of the elastic properties as a function of magnetic field has allowed critical fields to be determined, and the variation of the elastic moduli with pressure have allowed the Grüneisen parameters and third order elastic constants to be calculated. Results have been compared where possible with earlier published findings.
