Systematic effects of carbon doping on the superconducting properties of Mg(B${}_{1-x}$C${}_x$)${}_2$

R. H. T. Wilke, S. L. Bud'ko, P. C. Canfield +3

The upper critical field, $H_{c2}$, of Mg(B${}_{1-x}$C${}_x$)${}_2$ has been measured in order to probe the maximum magnetic field range for superconductivity that can be attained by C d…
