Abstract
We report the preparation of Mg1-xLixB2 compounds. Nearly single phase samp les were obtained for x less than or equal to 0.3. The in-plane lattice par ameter a decreases with Li doping, while the lattice parameter c does not s how obvious change. The superconducting transition temperature of Mg1-xLixB 2 decreases with Li doping and loss of superconductivity occurs for x = 0.5 sample. The results were discussed in terms of the T-c dependence on hole doping and contraction of the lattice parameter a. (C) 2001 Elsevier Scienc e B.V. All rights reserved.
