Dielectric properties: permittivity, loss factor, tan delta and ionic conductivity of nanostructured ferrites have been measured. Samples used were nickel, zinc and yttrium doped ferrites mixed in various ratios. The synthesis has been performed using precipitation method and obtained powders were pressed in pellets under varying pressure. X-ray diffractography approach for the refinement of structure and microstructural analysis has been performed. All parameters have been measured in 1 Hz to 100 kHz frequency range and 30 °C to 80 °C temperature range. Significant improvements in permittivity, loss factor and ionic conductivity comparing to bulk samples have been observed. © 2007 American Institute of Physics [ABSTRACT FROM AUTHOR] |
