Upper Critical Field of Superconducting MagnesiumDiboride )

摘要

In this paper the author addresses the nature of upper critical field of magnesium dioxide ( MgB_(2) ) using? Ginzberg- Landau (GL) approach. Nowadays, Superconducting materials show promising progress for the technological applications. According to this and previous studies, magnesium diboride is one of the superconducting materials which has relatively better critical temperature. The work will focus on determination of critical field and temp. of the material.
