Abstract

Superconductivity and structural properties of Mg1-xAlxB2 materials have been systematically investigated. Evident modifications in both superconductivity and microstructure are identified to originate from the Al ordering along the c-axis direction. The resultant superstructure phase has an optimal composition of MgAlB4 with the superconducting transition at around 12K. Brief diagrams illustrating the superconductivity and structural features of Mg1-xAlxB2 materials along with the increase of Al concentration are presented.
