Abstract
The separated electrostriction tensor components have been measured for single‐crystal calcium fluoride by the converse effect, using a specially designed uniaxial elastic stressing jig. Values obtained for the individual components of the electrostrictive voltage (M) coefficients were M11=−0.132, M12=0.117, and M44=0.507 in units of 10−20 m2/V2. These values are smaller than those observed by direct measurement of electric‐field‐induced elastic strain (K. Rittenmyer, Ph.D. thesis, The Pennsylvania State University, 1984), but are closer to expected values and likely to be more reliable.This publication has 5 references indexed in Scilit:
