摘要：
From polarization-electric field (P-E) results of the (1-x)Pb(Yb1/2Nb1/2)O-3-xPbTiO(3) ((1-x)PYN-xPT, 0.30 <= x <= 0.70) solid solutions tested at room temperature, remanent polarization (P-r) and coercive field (E-c) values with composition ranges of 0.30 <= x <= 0.40 tended to increase gradually. In the composition of 0.46 <= x <= 0.56 including the morphotropic phase boundary (MPB), the P-r values decreased as a whole, but the E-c values increased. For the temperature effect, the area of hysteresis loops in the composition of 0.44 <= x <= 0.50 decreased from room temperature to 220 degrees C, which shows the typical characteristics found in ferroelectrics. Piezoelectric measurements revealed a maximum piezoelectric constant (d(33)) of 302 pC / N at x = 0.50.
