Study of Ni and Zn doped CeOFeAs: Effect on the structural transition and specific heat capacity
S. J. Singh, Jai Prakash, A. Pal +3
We have systematically studied the substitution of nonmagnetic Zn and magnetic Ni at iron sites in Ce based oxypnictide. The parent compound (CeOFeAs) shows an anomaly in resistivi…

Enhancement in transition temperature and critical current density of CeO0.8F0.2FeAs by yttrium doping
J. Prakash, S. J. Singh, A. Banerjee +2
We report significant enhancement in superconducting properties of yttrium substituted Ce1-xYxOFFeAs superconductors. The polycrystalline samples were prepared by two step solid st…

Potassium fluoride doped LaOFeAs multiband superconductors: Evidence for extremely high upper critical field
S. Singh, J. Prakash, D. Srikala +3
We describe a new methodology of synthesizing the oxypnictide superconductors with potassium fluoride as a source as a source of fluorine instead of LaF3. This route also allows th…
