• We have studied the impact of simultaneous Ba super(2+) doping at Sm super(3+) site (hole doping) and F super(-) doping at O super(2-) site (electron doping) on the structural and superconducting properties of Sm1111 system using a single source, BaF sub(2). With BaF sub(2) doping the extent of layering of the grains and the grain size have been improved considerably. High transport current of 875 A/cm super(2) at 12 K has been achieved for the doped sample. The binary doped sample shows higher T sub()cof 51 K than the corresponding F-alone doped sample. In addition, substantially high values of H sub()c2and better J sub(c)-H behavior are observed for the BaF sub(2) doped samples. These results strongly indicate the scope for SmFeAsO based conductors with higher current carrying capacity.
