The Static Current Density–Electric Field characteristics of Sr(MnTi) x F e (12‐2x) O 19 ferrite compositions ( x = 0.5, 1.0, 1.5, and 2.0) have been investigated from 4.15 to 36.30 kV/m at room temperature. Ohmic and nonohmic regions are observed at low and high field regimes. The various models, governing nonlinear conduction, are discussed qualitatively in terms of Space charge limited current ( SCLC ), Ionic hopping, Poole–Frenkel, Schottky–Richardson, and Fowler–Nordheim mechanisms. The results depict Child‐Langmuir type SCLC in the investigated compositions.
