摘要：

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 (similar to1%) and the presence of Mg vacancies (similar to5%) resulted in lowering the T-c by only 2 K. (C) 2001 American Institute of Physics.
