Dielectric relaxor and ferroelectric relaxor: Bi-doped paraelectric SrTiO3

In this article, we report the evolution of the dielectric behavior from a dielectric relaxor to a ferroelectric relaxor with variation of Bi concentration in (Sr121.5xBix)TiO3 (0<x<0.2). In the doping range 0.0005<x<0.002, two dielectric modes A and B are induced. The temperature (Tm) where the permittivity maximum occurs for modes A and B is independent of Bi concentration and of dc electric ...

A Temperature-Dependent Hysteresis Model for Relaxor Ferroelectric Compounds

This paper summarizes the development of a homogenized free energy model which characterizes the temperature-dependent hysteresis and constitutive nonlinearities inherent to relaxor ferroelectric materials. A kernel for the model is developed through mesoscopic energy analysis and extended to provide macroscopic constitutive relations through stochastic homogenization techniques based on the as...

Optical bistability in Er-Yb co-doped phosphate glass microspheres at room temperature

We experimentally demonstrate optical bistability in Er-Yb phosphate glass microspheres at 295 K. Bistability is associated with both Er fluorescence and lasing behavior, and chromatic switching. The chromatic switching results from an intrinsic mechanism exploiting the thermal coupling of closely-spaced energy levels, and occurs simultaneously with the intensity switching. A contrast ratio of ...

Room-temperature ferroelectric polarization in multiferroic BiMnO3

Single-phase multiferroic BiMnO3 ceramic was synthesized via high-pressure and high-temperature solid-state reaction. Microstructure modification accompanied by emergence of superlattice due to electron-beam irradiation was observed wherein by means of electron diffraction (ED) combined with high-resolution transmission electron microscopy (HRTEM). It was clearly evidenced that the well-establi...

Room Temperature Ferromagnetism in Cobalt Doped ZnO Nanoparticles

In this work we report synthesis and magnetic characterization of cobalt doped ZnO nanoparticles (with different percent of doped cobalt oxide). Synthesis of the materials was carried out at room temperature by polyacrylamide-gel method, using zink sulfate and cobalt nitrate as source materials, acrylamide as monomer and N,N-methylene bisacrylamide as a lattice reagent. Characterization of the ...
