5.2. Co-effect of ball milling and C doping on the superconducting properties 63 method using the 1µV cm −1 criterion. T c values obtained for the C-doped wires show a decrease of 1.5 K to 2.5 K when compared to their corresponding reference wires, that is, non-doped wires with the same milling conditions. This would mean that the average C ...
