Anomalous Raman scattering from phonons and electrons of superconducting FeSe
Pradeep Kumar, Anil Kumar, Surajit Saha +6
We report interesting anomalies in the temperature dependent Raman spectra of FeSe measured from 3K to 300K in the spectral range from 60 to 1800 cm and determine t…
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)…
Upper critical field, superconducting energy gaps, and Seebeck coefficient in La0.8Th0.2OFeAs
J. Prakash, S. J. Singh, S. Patnaik +1
We report the synthesis and characterization of a new electron-doped La-oxypnictide superconductor by partial substitution of lanthanum by thorium. The superconducting transition t…
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…
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.…
