Discriminating Lattice Structural Effects from Electronic Contributions to the Superconductivity of Doped MgB 2 with Nanotechnology

Abstract

Most partial altervalent/aliovalent substitutions for Mg or B in MgB2 studied to date depress the superconducting transition temperature (Tc) and, at higher replacements, completely suppress superconductivity of MgB2. The diminution and loss of superconductivity in MgB2 arise from the subtle interplay between the competing/ cooperating effects of the… (More)
