Abstract

Two series of Mg-Mn ferrites with the substitution of Sm3+ and or Zr4+ having the chemical compositions Mg0.95 Mn0.05 Sm2x Fe2-2x O4 and Mg0.95 Mn0.05+x ZrxFe2-2x O4 have been prepared. Two types such as bulk as well as nano size particles ferrite materials are prepared for relative studies of these materials. Dielectric properties such as dielectric constant, complex dielectric constant and dielectric loss tangent along with AC resistivity are investigated in the frequency range 1 Hz to 10 MHz and temperature range -150 to 300°C. The value of x varies from 0.0 to 0.5 in steps of 0.1. The obtained experimental results of dielectric constant, loss factor, and AC resistivity of bulk size ferrites are compared relative to nano size ferrites.
