“…Our sample's s values are fewer than one, indicating that the transport mechanism is connected with localized electron hopping. [66] We notice that the value of s rises with the temperature increase, implying that the conduction process may be explained by the non-overlapping small polaron tunneling mechanism (NSPT).…”

The development of multifunctional materials is an exceptional research area, which is aimed at enhancing the versatility of materials according to their wide fields of application. Special interest was devoted here to the orthophosphate compound, in particular, the olivine NaMnPO4 material. This compound was successfully synthesized by a solid‐state method and characterized using various techniques. Preliminary room‐temperature structural analysis evidences the sample formation in the orthorhombic structure and its phase purity. The material’s morphology, analyzed by scanning electron microscopy (SEM), is identified by a spherical grain size distribution. The average grain size of the sample was estimated to be around 420 nm. Moreover, the optical investigation of UV‐visible spectroscopy has revealed that the band gap for our sample is (Eg = 2.28 eV), which shows that our compound is a potential candidate for optoelectronic applications. The electrical behavior study's main results confirm the ferroelectric character of the sample and support the aim of deepening the knowledge of the material according to its thermally stimulated conduction processes through impedance spectroscopy. Electrical studies revealed the dominant transport processes across various temperature and frequency ranges, leading to the NSPT model. The frequency dependency relates to frequency‐dispersive dielectric spectra, conduction mechanisms, and relaxation phenomena.

“…4,5 It is found that Ba(Zr x Ti 1Àx )O 3 (BZT), obtained by the B-site substitution of BaTiO 3 , [6][7][8][9] can effectively lessen the leakage current density and residual polarization, while increasing the breakdown field strength. [10][11][12] With the increase of Zr content, BZT can be transformed from ferroelectric material to relaxor ferroelectric material. When zirconium content increases to 35%, Ba(Zr 0.35 Ti 0.65 )O 3 (BZT35) exhibits complete relaxor ferroelectricity and typical relaxor behavior can be observed.…”

“…Among the important characteristics of this pseudo-binary ferroelectric BCZT is the existence of a triple point in the previously studied BZT-BCT diagram, located at x=0.32 where this region is considered as a separation between the rhombohedral and the tetragonal symmetry and corresponds to a high permittivity and huge electromechanical coefficients [11].…”

Effect of Mn doping on structure, the dielectric and electric properties of BCZT ceramics

The synthesis of (Ba0.99Ca0.01)(Zr0.2Ti0.8)O3 (BCZT) and doped (Ba0.99Ca0.01)(Zr0.2Ti0.8-xMnx)O3 (BCZT-xMn) ceramics was successfully carried out by the solid-state method. The doping effect is followed by X-ray powder diffraction, scanning electron microscopy (SEM), and dielectric and conductivity measurements. Indeed, X-ray diffraction measurements show the crystalline structure of ceramics. SEM images indicate the doping effect on the studied perovskite microstructure. The results indicate that during doping the maximum value of the temperature (Tm) of the dielectric constant varies slightly, and there will be a considerable decrease in permittivity, dielectric losses and conductivity. Manganese ions are well integrated in the perovskite while maintaining the solid solution.
