STRUCTURE ANALYSIS OF NEW SUPERCONDUCTOR MgB2

摘要

The superconductivity of a sintered pellet of the newly discovered MgB2 superconductor has been studied withrnmagnetic measurements and its crystal structure was analysed using the Rietveld method of powder X-ray patterns. Itrnhas hexagonal symmetry (S.G. P6/mmm) with unit cell lattice parameters a=0.308136(14)nm and c=0.351782(17)nm.
