| Popis: | The out-of-plane resistance of BSCCO-2212 single crystals with T c0 =91–93 K has been measured in magnetic fields up to 50 T over a wide temperature range. The results are characterized by a positive linear magnetoresistance in the superconducting state and a negative linear magnetoresistance in the normal state. We show that the zero-field normal state c -axis resistance, the negative linear normal state magnetoresistance and the divergent upper critical field, H c2 , may be understood within the framework of the bipolaron theory of superconductivity. |
