The influence of Nb2O5 additive (0 − 5 wt. %) on elastic and dielectric properties of Ni0.4Cu0.3 Zn0.3 Fe2O4 ferrite synthesized by the sol–gel method was studied in the present study. The longitudinal and shear wave velocities were measured by ultrasonic pulse transmission method. The elastic constants increased as the Nb2O5 contents increased. LCR-Q meter was used to study the dielectric properties in 50 Hz to 5 MHz frequency range. The dielectric parameters such as dielectric constant (ɛ′) and dielectric loss tangents were decreased with increased frequency and Nb2O5 additive composition for all investigated samples at room temperature revealing normal dielectric behavior of ferrites. The variations in the dielectric constant (ɛ′) and dielectric loss tangents values were explained using Maxwell–Wagner interfacial polarization according to Koops phenomenological theory. Also, there is increase in the AC conductivity was increased with an increase in the frequency whereas reduction in AC conductivity with the rise in concentration of Nb2O5 additive. |
