TL;DR: In this paper, a new empirical equation for a phenomenological description of the temperature dependence of the dielectric permittivity (e') peak is proposed, which provides an excellent fitting of the experimental curves at temperatures into and above the dispersion region, enabling us to calculate some characteristic parameters of the phase transitions in ferroelectric materials.

TL;DR: In this paper, the most common methods for determining the dc electrical resistivity in solid materials are discussed and a brief overview of the fundamental concepts related to the electrical resistivities on materials is introduced.

TL;DR: In this article, the synthesis, structural, microstructural and magnetic properties of high-energy ball milled BiFeO3 and Bi0.95Eu0.05 powders were thoroughly investigated through X-ray diffraction, scanning electron microscopy, Mossbauer spectroscopy and magnetization measurements.

TL;DR: In this paper, structural, electric, magnetic, and Mossbauer spectroscopy studies were conducted in (x)BiFeO3−(1-x)BaTiO3, 0.9 ≥ x ≥ 0.3, solid solutions.

TL;DR: In this article, the structural and spectroscopic characterization of transparent lead lanthanum zirconate titanate ceramics doped with Nd3+, Er3+, or Yb3+ ions is presented.
