The Study Of The Electronic Thermal Conductivity Of Superconducting Magnesium Dlboride (mgb2)

For magnes ium diboride (MgB2)' some of th e superconducting pmperlies that have beenrnstudied are summari zed. The energy di spersion relation is determined and it is used torndeterm ine the electmnic thermal conductivity of MgB2. From that energy functi on. thern, ,rnexpression for the elec tronic heat capac ity of magnesium diboride in normal state hasrnbe~n determ·ined. ·Tile general ex pression of the electmnic thermal conducti vity for MgB ~rnin normal state i ~ fo und. Then, by taking th e energy gap parameter in to account thernelectmnic then;lal conductivity has been computed for the superconducting state of ourrnmaterial ; that is belO'- tbe transition temperatu re. Then, th e electroni c thermalrnconductivit) of magnesium diboride has been plotted as a function of tempe ratu re with inrnthe superconducting state. Moreover, the electrical conducti vity of MgB2 is calcu latedrnand the Wiedemann-F ranz law is checked fo r normal sta te of a material. Finally. therngeneral expression for electronic thermal conducti vity of MgB2 is determined in K -rnSpacernKey Words: Magnesium chloride. thermal conductivity. superconducting state
