Research Abstract

In this study, we have explored and attempted to establish an effective method to improve superconducting properties of magnesium diboride(MgB_2) wire which is a promising material for the next generation of magnetic resonance imaging(MRI) magnet. The result makes it clear that the addition of pyrene(C_<16> H_<10>) powder leads to disorder in MgB_2 lattice and an increase in irreversibility field which is one of the most important criterions for superconducting application. The findings also show that the in-field critical current density is considerably improved by carbon distribution due to pyrene gas and the ductility of coarse Mg powder.
