The characteristics of a new ferroelectric measurement system at the European Synchrotron Radiation Facility are presented. The electric-field-induced phase transitions of Pb(Mg(1/3)Nb(2/3))O(3)-xPbTiO(3) are determined via in situ measurements of electric polarization within the synchrotron diffraction beamline. Real-time data collection methods on single-crystal samples are employed as a function of frequency to determine the microstructural origin of piezoelectric effects within these materials, probing the dynamic ferroelectric response.
介绍了一种新型铁电测量系统在欧洲同步辐射设施中的特点。通过在同步辐射衍射线束内进行电致极化的原位测量,确定了 Pb(Mg(1/3)Nb(2/3))O(3)-xPbTiO(3) 的电场诱导相转变。采用单晶样品的实时数据采集方法,作为频率的函数,以确定这些材料中压电效应的微观结构起源,探测动态铁电响应。
