Anisotropic normal-state properties of the MgB2 superconductor

Based on the experimentally-found existence of two superconducting gaps in M-B, (one gap associated to the boron g-states and the other to the boron pi-states), the different contributions to the transport properties, electrical conductivity and Hall coefficient were studied using the full potential...

Sumario:Based on the experimentally-found existence of two superconducting gaps in M-B, (one gap associated to the boron g-states and the other to the boron pi-states), the different contributions to the transport properties, electrical conductivity and Hall coefficient were studied using the full potential-linearized augmented plane wave method and the generalized gradient approximation. Four different relaxation times were needed to adjust the electrical conductivity and Hall coefficient to experimental values. MgB2 doping was analysed in the rigid band approximation
