Abstract
The single-phase sample of MgB2 was prepared successfully at the temperatur e of 900 degreesC and under the pressure of 3 GPa. The structure of the sam ple was investigated using powder X-ray diffraction and Rietveld analysis. The results show that the structure of the sample belongs to the hexagonal structure with space group of P6/mmm, a=3.0861(5) Angstrom, c=3.5222(8) Ang strom. The magnetic and resistance measurements indicate that the supercond ucting transition temperature T-c is 39 K.
