Beschreibung:
<jats:p>The electroelastic effect of α quartz is investigated by means of high-resolution measurements of ultrasonic transit times as a function of a superimposed biasing field. Experimental results are reported for 25 different configurations of wave normal, displacement, and electric field vectors. It is shown that these results may consistently by expressed in terms of an effective fifth-rank tensor with eight independent components.</jats:p>
