PrOFe0.9Co0.1As is known to be a superconductor with a TC of ~ 14 K. In an attempt to induce charge transfer and also induce chemical pressure between the FeAs and PrO layers we have synthesized for the first time oxypnictides of the type PrOFe0.9Co0.1As1 − xPx (P doping at As sites). All the compounds crystallize in the tetragonal ZrCuSiAs-type structure (space group = P4/nmm). The lattice parameters (a and c) decrease as expected on substitution of smaller phosphorus at the arsenic site in… Expand

Doping dependence of the upper critical field, superconducting current density and thermally activated flux flow activation energy in polycrystalline CeFeAsO 1- x F x superconductors
Abstract We report the results from resistivity and magnetic measurements on polycrystalline Ce oxypnictide (CeFeAsO 1– x F x ) samples where x spans from 0.13 to 0.25. We find that the orbitalExpand


Two-band superconductivity in LaFeAsO0.89F0.11 at very high magnetic fields
It is argued that oxypnictides represent a new class of high-field superconductors with Bc2 values surpassing those of Nb3Sn, MgB2 and the Chevrel phases, and perhaps exceeding the 100 T magnetic field benchmark of the high-Tc copper oxides. Expand

New oxypnictide superconductors: PrOFe1−xCoxAs
Abstract Oxypnictides of the type PrOFe1−xCoxAs (x≤0.3) were synthesized for the first time by the sealed tube method. All the compounds were found to be monophasic and crystallize in the tetragonalExpand
Superconductivity at 43 K in an iron-based layered compound LaO1-xFxFeAs
It is reported that increasing the pressure causes a steep increase in the onset Tc of F-doped LaOFeAs, to a maximum of ∼43 K at ∼4 GPa, which is the highest Tc reported to date. Expand
