Abstract
The static current density (J)-electric field (E) characteristics of SrCoxTixFe(12−2x)O19 ferrite compositions (x = 0.0, 0.2, 0.3, 0.5, 0.6, 0.7, 1.0) have been investigated from 0.07 kV/m to 5.29 kV/m at room temperature. All compositions obey Ohms Law at low applied field and non-linearity conduction is observed at high field in compositions x = 0.0, 0.2, 0.3, 0.5, 0.6 and 1.0. The non-linear conduction mechanisms, Schottky, Poole-Frenkel, Ionic Hopping and Space Charge Limited Current mechanism, have been discussed. The current density is increased at higher substitution.
