The Characteristic shape of resistivity transitions in HTS under magnetic field interaction is mysterious. The magnetoconductivity tensors σxx & σxy  in case of Y123 has been computed under radiofrequency excitations 1-6 MHz range at H=8000G [1]. The Bi2212 characteristics curves Hall potential VH, Hall coefficient RH and magnetodynamically stimulated density of electrical carriers NH along with the temporal development of magnetopotential records had been observed to relate the magnetoresistivity [2,3]. The normal resistivity and conductivity of HTS Bi2212 between superconducting transition temperature below 100K to above 300K had been depicted. The localized density of states is observed to create anisopropy and the oscillatory behaviour of all these parameters even at room temperatures [4,5].

Keywords: Magnetoconductivity tensors, Hall geometry, Electrical carrier density.
