中文摘要 | We report the preparation of Mg1-xMxB2 (M = deficiency or Ca) compounds and their structure and superconducting properties. For Mg1-xB2, although nearly single-phase samples can be obtained for x = 0, MgB4 coexists with the MgB2 phase and some minor impurity phases. and the amount of MgB4 increases with x for 0 < x &LE; 0.5. The lattice parameters a and c of MgB2 decreases and increases, respectively, with the increase of x. and T-c also decreases. While for Mg1-xCaxB2, the superconducting transition temperature remains unchanged for x &LE; 0.3 and loss of superconductivity occurs for x > 0.3. X-ray diffraction patterns for x less than or equal to 0.3 samples show that MgB2 phase coexists with CaB6, Mg, and MgO. With increasing x. the amount of CaB6, Mg, and MgO increases. while the amount of MgB2 decreases. The lattice parameters of MgB2 phase do not show any obvious change in contrast to Mg1-xB2. The results were discussed by considering some possible contributions. |
