Magneto-Hall coefficient

The problem with Eqs. (5) and (6) is that the terms Sps and SRs introduce four new parameters two magnetoresistance coefficients ( and p), and two magneto-Hall coefficients (/S and Pp). These coefficients are defined by Eqs. (A29) and (A32), respectively, in Appendix A, but unless they are known independently, we cannot uniquely determine n, p, pn, and pp from this analysis. 

The application of a magnetic field on a MIEC placed in a galvanic cell affects the current density equation which now contains also the effect of the Lorentz force.The use of a magnetic field should enable the determination of the Hall coefficient and magneto resistance. The interpretation of the results is straightforward and can be done in terms of the two-band semiconductor modeF when the composition of the MIEC is uniform and there is one dominant mobile ionic species and one dominant electronic species. Uniformity holds when the two electrodes have the same composition, are reversible, and a steady state has been reached.
