| Abstract | The dependence of the critical temperature Tc on the pressure P in the magnesium diboride MgB2 has been studied inthe two-band model. In each band consists of two pairing interaction, electron-phonon interaction and non-electron-phononinteraction. This research derived the exact equation of the critical temperature dependence on pressure for magnesium diboridesuperconductor. It was found that increasing electron-phonon coupling constant and non-electron-phonon coupling constant of 1stand 2nd band will increase the Tc. The critical temperature decreased as pressure increased and can be fitted well to theexperimental Tc versus P in magnesium diboride. |
