Ultra-broad-band dielectric spectroscopy and phonons in (Pb1-x/2Lax)(Zr0.9Ti0.1)O3.
Original language description
The dielectric behavior of (Pb1x/2Lax)(Zr0.9Ti0.1)O3 PLZT 100x/90/10 (0 100x 1) was studied in the frequency range 102?1014?Hz using dielectric, time-domain terahertz (THz), far-infrared, and Raman spectroscopy in the temperature interval 10?900 K. PZT 90/10 and PLZT 2/90/10 undergo two phase transitions, from a cubic paraelectric to a rhombohedral untilted ferroelectric (FE) phase and on further cooling to a tilted FE phase. PLZT 4/90/10 and PLZT 10/90/10 are incommensurately modulated and composed ofan intergrowth of polar and antipolar cation displacements. These samples consequently demonstrate a FE soft mode which exhibits minimal frequency several tens of degrees above the nominal antiferroelectric phase transition temperature. The dielectric response of PLZT 100x/90/10 is mainly governed by a gigahertz relaxation and a soft phonon component in the THz range.
