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 $^{\circ}$ C.

The result shows that the value of temperature of resonant frequency $(τ_{f})$ 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 $(τ_{f})$ . By doping a compound such as CaTiO₃ which has a very positive temperature of resonant frequency ( $τ_{f} = 712$ ppm/ $^{\circ}$ C) and a very high relative permittivity $(𝜀_{r} = 145)$ , 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.
