AB  - The dielectric properties of Neodymium zinc titanium oxide (NZT) and Neodymium magnesium titanium oxide (NMT) were investigated. The single-phase ceramic was synthesized at various temperatures below 1650∘  C.  The result shows that the value of temperature of resonant frequency (τf)  for NMT is higher than NZT.  Our findings also indicate that the rare earth materials produce high property dielectric materials, despite the fact some elements produce lower negative value of temperature of resonant frequency (τf) . By doping a compound such as CaTiO3 which has a very positive temperature of resonant frequency (τf=712 ppm/∘C) and a very high relative permittivity (εr=145), it is possible to tune NZT and MNT to achieve an excellent dielectric material. This work is under consideration. The results of this scientific research could be very important for modern advance applications in microelectronic miniaturization.

AB  - Neodymium zinc titanate (NZT) is a very attractive perovskite due to its magnetic and dielectric properties. Considering the microstructure influence NZT stability and performance, it is of great importance to establish an approach for the analysis and prediction of grain boundary phenomena. The fractal nature analysis has already proved to be valuable for the reconstruction and prediction of ceramics intergranular electrical properties. However, no researches were performed on the fractal analysis applied on magnetic materials. This method could give an insight in magnetic properties change from the bulk to the grain interface level. In this study, fractal analysis was applied for the Curie-Weiss law correction, introducing fractal correction into magnetic materials for the first time. NZT powders used in this research for fractal analysis were obtained after sintering at different temperatures in the range from 1450°C to 1675°C.Connection between the microstructure fractal nature and the resulting magnetic permeability has been established, enabling the application on different magnetic materials in the future. This creates a foundation for new researches that will lead to further miniaturization of satellite and mobile devices.

AB  - In this paper we present the research results on dielectric properties based on Rare earth Neodymium Zinc Titanites (NZT). These results show that we have a stable perovskite structure and the other structure search suggest that the monoclinic crystal structure could be proposed for NZT. Modelling and simulation were used in this research to define the atomic position and crystal structure of NZT. The compositions have very specific dielectric properties which could useful in microwave telecommunications. It is very important to reduce the size, weight and microelectronic devices coast for future applications. So, the new miniaturization, better packaging and higher level of integrations, by using multi-layer processes and advanced interconnection methods are very important for modern telecommunications. In that sense, some new results and knowledges about fractal nature in materials, electronic ceramics and perovskites are very important for new fractal microelectronics applications for modern communications and IT technologies. Instead of classic semiconductor technologies, which are not anymore so much perspective and promising in this area. Finally, all of these aspects are very important for microanthena systems in telecommunications.

AB  - Using the high -resolution x-ray diffraction (XRD) analysis, scanning electron microscopy (SEM), and temperature-dependent microwave resonator characterization the dielectric properties and phase assemblage of Rare earth Neodymium Zinc Titanite (NZT) was investigated in this research work. NZT ceramics samples were prepared via mixed oxide. The result shows that it is distrustful to be a stable perovskite structure, in fact something comparable to Ilmenite structure, nevertheless further research shows that the monoclinic structure can be purposed for NZT. The Modelling and simulation were used in this study to define the atomic position and structure of NZT. In conclusions, single-phase ceramics of NZT; have been synthesised at every sintering temperature 1250-1675°C. NZT has the temperature coefficient of resonant frequency 47 MK-1, Quality factor was 42000 at frequency of 4.33 GHz and relative permittivity 36. The crystal structure of NZT is monoclinic with Bravais Lattice P and space group of P21/n. Kikuchi line shows that this material has a single phase. These compositions have promising dielectric properties and can be used in microwave telecommunications.
