The results from magnetotransport and magnetization of nanodiamond doped MgB₂-nD_x are reported. Superconducting transition temperature (T_c) is not affected significantly by x up to x =0.05 and latter decreases slightly for higher x>0.05. R(T) vs H measurements show higher T_c values under same applied magnetic fields for the nanodiamond added samples, resulting in higher estimated Hc₂ values. From the magnetization measurements, it was found that irreversibility field value H_irr for the pristine sample is 7.5 T at 4 K and the same is increased to 13.5 T for 3 wt % …
