“…Otherwise, it must be emphasized the value of θ c is smaller than θ ε , what is until now not clear. Similar difference was reported by O. N. Ivanov et al [15] that measured dielectric and elastic properties in PbFe 0.5 Nb 0.5 O 3 material.…”

Ferroelectric materials have been extensively studied through their optical and dielectric properties. However, there are no many reports concerning simultaneously elastic and dielectric characterization. In this work, ferroelectric ceramics of SPT (x = 0.25) have been investigated by the ultrasonic pulse echo technique and dielectric measurements, as a function of the frequency and temperature. In the pulse echo technique, ultrasonic attenuation and velocity are obtained. The elastics constant stiffness was calculated from the ultrasonic velocity. The results obtained for dielectric and elastic modulus showed anomalies around the phase transition temperature, which can be correlated considering an elastic-electric linear coupling between strain and spontaneous polarization.

“…PFN is a perovskite material in which, in general, the chemical formula (ABO 3 ) lead ions are located in positions A, while iron and niobium ions are located in octahedral positions B (alternatingly) [ 29 , 30 , 31 , 32 ]. PFN shows two ordered antiferromagnetic and ferroelectric subsystems (the magnetic phase transition takes place at about −130 °C temperature, whereas the ferroelectric phase transition occurs at about 110 °C temperature) [ 33 , 34 ]. PFN is used as a dielectric and magnetic medium for multi-layer ceramic condensers and coils, multi-layer ceramic capacitors (MLCC) and inductors, multi-layer microwave resonators and filters as tunable transducers, electrostriction actuators, servomotors, microcontrollers, sensors, detectors, and memory devices [ 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 ].…”

This work presents the electrophysical properties of the multiferroic ceramic composites obtained as a result of combining both magnetic and ferroelectric material. The ferroelectric components of the composite are materials with the following chemical formulas: PbFe0.5Nb0.5O3 (PFN), Pb(Fe0.495Nb0.495Mn0.01)O3 (PFNM1), and Pb(Fe0.49Nb0.49Mn0.02)O3 (PFNM2), while the magnetic component of the composite is the nickel-zinc ferrite (Ni0.64Zn0.36Fe2O4 marked as F). The crystal structure, microstructure, DC electric conductivity, and ferroelectric, dielectric, magnetic, and piezoelectric properties of the multiferroic composites are performed. The conducted tests confirm that the composite samples have good dielectric and magnetic properties at room temperature. Multiferroic ceramic composites have a two-phase crystal structure (ferroelectric from a tetragonal system and magnetic from a spinel structure) without a foreign phase. Composites with an admixture of manganese have a better set of functional parameters. The manganese admixture increases the microstructure’s homogeneity, improves the magnetic properties, and reduces the electrical conductivity of composite samples. On the other hand, in the case of electric permittivity, a decrease in the maximum values of εm is observed with an increase in the amount of manganese in the ferroelectric component of composite compositions. However, the dielectric dispersion at high temperatures (associated with high conductivity) disappears.

“…The PFN material is characterized by two ordered antiferromagnetic and ferroelectric subsystems. A change from the paramagnetic to ferroelectric phase takes place at about −130 • C temperature, whereas a change from the paraelectric to ferroelectric phase occurs at about 110 • C temperature [4,5].…”

The PbFe 1/2 Nb 1/2 O 3 (PFN) ceramics can be obtained by a lot of ways. There are a lot of methods and techniques to synthesize the PFN powder such as: reactions in the solid phase by one-stage or two-stage synthesizing method (the columbite method), molten salt synthesis, sol-gel, co-precipitation method and sintering of compacts from a loose mixture of powders. Each of them requires accuracy and precision to conduct a technological process, aiming at obtaining a product with the optimum parameters. In the work PFN specimens were obtained by one-stage synthesis methods using two different powder synthesizing techniques: by calcining (sintering of a loose mixture of the PFN powder) and as a result of sintering of pressed compacts from the PFN powder mixture at high temperature (pressing). The obtained specimens were subjected to X-ray and micro-structural examinations and tests of internal friction and dielectric properties. The tests showed that the ceramics obtained by the powder calcining method has better applied properties.
