摘要：

The out-of-plane resistance of BSCCO-2212 single crystals with T-c0 = 91-93 K has been measured in magnetic fields up to 50T 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 held, H-c2, may be understood within the framework of the bipolaron theory of superconductivity.
