Description
In this work we synthesized both MgB2 and Carbon doped MgB2 superconductor with Ag addition via high energy milling and substituent heat treatment. Heat treatments were performed at 900 degree C for 30 min in flowing Ar gas. We varied amount of Ag powder. In a range of Ag powder was 0-5wt%. The effect of Ag was correlated with superconducting properties. The results show a slight decrease in critical temperature (Tc) and a reduction of critical current density (JC) at high fields for the Ag-doped samples as compared to the un-doped samples. Reduction of Jc may be due to the formation of MgAg compound.
