note = "Funding Information: The measurements reported in this paper were performed primarily in an effort to observe such a phase transition. The ultrasonic propagation velocity was measured using a coherent pulse - C. W. technique, as described by De Klerk \[5\], with a measurement frequency of about 200 MHz. The ultrasound was generated by a CdS transducer evaporated onto a \[100\] cleavage face of the sample. The end faces were flat to less than one optical fringe and sufficiently parallel that a good exponential ultrasonic echo train could be obtained up to several hundred megacycles.
