Abstract
Dielectric properties such as dielectric constant (epsilon'), dielectric lo ss tangent (tan delta) and complex dielectric constant (epsilon ") has been investigated in the frequency range 100 kHz-1 MHz. The variation of these parameters with composition, frequency and temperature is explained qualita tively. The dielectric constant for these ferrites is approximately inverse ly proportional to the square root of the resistivity. An attempt is made t o explain the possible mechanism.
