The longitudinal resistivity (ρ[sub xx]) and Hall coefficient (R[sub H]) were measured for MgB[sub 2] sintered under high pressure. We found that R[sub H] is positive like cuprate high-T[sub c] superconductors, and decreases as the temperature increases for 40 K

    The element substitution for Cu is usually used to investigate the mechanism of the high TC superconductivity in cuprates. However, it is still controversial how substitution suppresses superconductivity. We suggest that the suppression of superconductivity by doping is attributed to the local...
