FIG. 1.

Direction of the cut described by angle and the rotated reference frame ( ) associated with it. The cut direction changes in plane going from [001] to [111] and then to the [110] direction.

FIG. 2.

Effective coefficient as a function of the cut direction for three perovskites materials (pink), (blue), and (green). The data for electrostrictive constants are taken from Table I .

FIG. 3.

Dependence of ratio on the cut direction . —longitudinal effective electrostrictive coefficient, —two transversal effective electrostrictive coefficients (see Eq. (4) ). (a) Plotted for with coefficients from Ref. 13 . (b) For from Ref. 14 . (c) For from Ref. 15 .

Tables

Generic image for table
Table I.

Electrostrictive coefficients, which were used for calculations, for coefficients were taken from Ref. 13 , for from Ref. 14 , and from Ref. 15 . The values are written taking into account the factor of 2 as defined in Landolt-Bornstein. 19
