The dependence of the electronic transport properties of ferrite on crystal structure is not exceptional in comparison with other materials. So, you will have to consider the relevant phase diagrams of ferrite and establish what transport measurements have revealed for the transport properties in the regions of these phase diagrams relevant to you.

You may begin with the phase diagram attached. There are also two relatively old papers, dealing with the thermodynamic properties of Iron-Oxygen systems, by LS Darken and RW Gurry, which I similarly attach below.

 Thank you sir, for providing me good document and concepts. 

You are welcome Sunil.

    Dear Sunil,

   Perhaps your question is on the Verwey phase that these materials present as an special feature of them. For instance, the magnetite (the oldest ferrite known) has a Verwey temperature around 120 K undergoing a first-order structural phase transition (cubic to octahedral symmetries). At room temperature it is a half-metal while at temperatures below the Verwey transition it suffers a drop of conductivity 2 or 3 orders of magnitude,i.e. it is an insulator. The decrease of conductivity is due to a freezing of electron hopping between octahedral Fe atoms (Fe2+ and Fe3+). Thus we obtain a charge ordering in the unit cell directly related with the orbital order.

   More fundamentally speaking, this phase transition characteristic of the ferrites is produced by an electron-phonon coupling under strongly correlated electronic interactions as physical background. The mixture of these different interactions makes that even today the full understanding is not achieved for such transitions.
