Hall effect in the mixed state of superconducting MgB2

On the basis of a theoretical model for the Hall effect within the framework of BCS superconducting mixed state and considering our longitudinal nonlinear response equation, we derived an analytical expression for the mixed state Hall resistivity of MgB2. This equation enables one to compare quantitatively the experimental data with the theoretical model. We also propose some possible scaling relations for the temperature and field dependencies of the Hall resistivity of MgB2.
