Abstract
(Pb[Formula: see text]Ba[Formula: see text])[(Zn[Formula: see text]Nb[Formula: see text])[Formula: see text]Ti[Formula: see text]]O 3 relaxor-type ferroelectric ceramics was obtained via classical solid-state reaction. The hysteresis loop results were discussed in the frame of ergodicity criterium around the characteristic ferroelectric relaxor freezing temperature. Slimer hysteresis loops were observed below the freezing temperature reflecting an ergodic relaxor behavior. Above this temperature, estimated around 223[Formula: see text]K for the studied system, larger and unsaturated like ferroelectric hysteresis loops were observed. This temperature also coincides with the slope change on maximum polarization and inflection point of remnant polarization curves. Energy storage, energy loss and efficiency values were determined in a wide temperature range. While the recoverable energy density shows relatively low values (0.23[Formula: see text]J/cm 3 ), there are interesting behaviors for this parameter and for the efficiency, since the two physical quantities increase versus temperature and the efficiency even reaches the value of 97%.
期刊介绍:
The Journal of Advanced Dielectrics is an international peer-reviewed journal for original contributions on the understanding and applications of dielectrics in modern electronic devices and systems. The journal seeks to provide an interdisciplinary forum for the rapid communication of novel research of high quality in, but not limited to, the following topics: Fundamentals of dielectrics (ab initio or first-principles calculations, density functional theory, phenomenological approaches). Polarization and related phenomena (spontaneous polarization, domain structure, polarization reversal). Dielectric relaxation (universal relaxation law, relaxor ferroelectrics, giant permittivity, flexoelectric effect). Ferroelectric materials and devices (single crystals and ceramics). Thin/thick films and devices (ferroelectric memory devices, capacitors). Piezoelectric materials and applications (lead-based piezo-ceramics and crystals, lead-free piezoelectrics). Pyroelectric materials and devices Multiferroics (single phase multiferroics, composite ferromagnetic ferroelectric materials). Electrooptic and photonic materials. Energy harvesting and storage materials (polymer, composite, super-capacitor). Phase transitions and structural characterizations. Microwave and milimeterwave dielectrics. Nanostructure, size effects and characterizations. Engineering dielectrics for high voltage applications (insulation, electrical breakdown). Modeling (microstructure evolution and microstructure-property relationships, multiscale modeling of dielectrics).
