Strong electron-electron correlation and weak localization in CeO_{0.9}F_{0.1}Fe_{1-x}Co_xAs
S. J. Singh, J. Prakash, S. Patnaik +1
Electron-doping of the semimetal (CeOFeAs) by either fluorine (max Tc ~ 43 K)or cobalt (max Tc ~ 11 K) leads to superconductivity. Here we show the effect of transition metal (Co)…
Superconductivity in CeO_{1-x}F_xFeAs with upper critical field of 94 T
J. Prakash, S. J. Singh, S. Patnaik +1
We have successfully synthesized Ce based oxypnictide with fluorine doping (CeO_{1-x}F_xFeAs) by a two step solid state reaction method. Detailed XRD and EDX confirm the crystal st…
Enhancement in superconducting transition temperature and upper critical field of LaO0.8F0.2FeAs with antimony doping
S. J. Singh, J. Prakash, S. Patnaik +1
We report the synthesis and characterization of antimony doped oxypnictide superconductor, LaO0.8F0.2FeAs1-xSbx (x = 0.05 and 0.10). The parent compound LaOFeAs with fluorine dopin…
Superconductivity at 11.3 K induced by cobalt doping in CeOFeAs
J. Prakash, S. J. Singh, S. Patnaik +1
Pure phases of a new oxyarsenide superconductor of the nominal composition CeOFe0.9Co0.1As was successfully synthesized by solid state reaction in sealed silica ampoules at 1180 C.…
