Influence of the upper critical field anisotropy on the transport properties of polycrystalline MgB${}_2$

M. Eisterer, C. Krutzler, H. W. Weber

The intrinsic properties of MgB${}_2$ form the basis for all applications of this superconductor. We wish to emphasize that the application range of polycrystalline MgB${}_2$ is limite…
