摘要：
The static current density (J)-electric field (E) characteristics of CaCoxTixFe(12−2x)O19 ferrite (x = 0.1,0.2,0.3,0.4,0.5,0.6,0.7) have been investigated from 0.06 kV/m to 4.10 kV/m at room temperature. Ohmic behavior is present in compositions x = 0.1,0.2,0.4,0.5,0.6,0.7 at low applied field, whereas non linearity in J-E curves is defined at higher applied region in compositions x = 0.2,0.3,0.4,0.7. The role of various conduction mechanisms Schottky, Poole-Frenkel, Ionic Hopping and Space Charge Limited Current mechanisms has been discussed.
