摘要：
The dielectric properties such as dielectric constant both real and imaginary part, dielectric loss factor, and AC resistivity have been studied in this work on mechanically alloyed Ni0.5Zn0.5Fe2O4 nano ferrite particles sintered from 700 to 1200 degrees C as a function of frequency in the range of 0.1 Hz to 15 MHz. The dielectric constant (epsilon') decreases with increase in sintering temperature and the decrease is explained with proper mechanism. The samples sintered at 900 and 1200 degrees C show slightly high epsilon' value compared to their predecessor. The AC resistivity at room temperature is found to be of the order of 10(9) Omega-cm.
