Piezoelectric and electro optic properties of tetragonal (1 − x)Pb(Mg1/3Nb2/3)O3− xPbTiO3 single crystals by phenomenological theory |
Dielectric constants ε 33 of (1 − x )Pb(Mg1/3 Nb2/3)O3– x PbTiO3 single crystals. Solid lines are the theoretical results calculated by eighth-order Landau–Dovenshire theory. Scattered dots are experimental observations originated from Ref. [ 14 ] for x = 0.38 (a), and Ref. [ 15 ] for x = 0.4 (b). |
