چکیده انگلیسی
Solid solutions of lead zirconate magnesium niobate Pb1âxLax[Zr0.9Mg(0.1+x)/3Nb(0.2âx)/3]O3 (0âxâ0.05) doped with lanthanum ions were prepared. By the analysis of temperature-driven transitions and experiments in strong electric fields, we determined the concentration and temperature intervals of the existence of antiferroelectric and ferroelectric states. X-ray diffraction proved that the antiferroelectric phase, stable with Ñ
>0.0175 at TC >Т >45 °C (during the cooling process at zero field), underwent a monoclinic distortion of perovskite cell and showed a disturbed translational symmetry of the orthorhombic superstructure. The energy storage density and electrostrictive strain were measured in the process that induces the antiferroelectricâferroelectric phase transitions.
