Influence of Zr/Ti on Dielectric Behaviour of Mn-Zn Ferrites

抄録

  The variation of dielectric constant (∈) for Zr/Ti substituted Mn-Zn ferrites have been studied as a function of dopant concentration, frequency and temperature. The dielectric loss (tan δ) is also studied for all the materials varying the dopant concentration as well as frequency. Results are interpreted based on the existing theoretical models. The maximum tan δ is found to be occur at 10KHz for Ti doped ferrites, unlike Zr doped ferrites exhibit this type of behaviour.
