Abstract

The influence of lattice strain and Mg vacancies on the superconducting properties of MgB₂ samples has been investigated. High quality samples with sharp superconducting transitions were synthesized. The variations in lattice strain and Mg vacancy concentrations were obtained by varying the synthesis conditions. It was found that high strain (∼1%) and the presence of Mg vacancies (∼5%) resulted in lowering the T_c by only 2 K. © 2001 American Institute of Physics.
