Critical properties of superconducting Ba1-xKxFe2As2
A. Bharathi, Shilpam Sharma, R. Paulraj +3
Magnetisation and magnetoresistance measurements have been carried out on superconducting Ba1-xKxFe2As2 samples with x=0.40 and 0.50. From low field magnetization data carried out…
Drastic ground state changes induced by Ni substitution in NaxCoO2
N. Gayathri, M. Premila, A. Bharathi +3
We report on the effect of Ni substitution at the Co site on the physical properties of NaxCoO2 system by investigating the series NaxCo1-yNiyO2 (x=0.75, 0<y<0.15). An upturn in th…
Raman Scattering Investigation of Electron Phonon Coupling in Carbon substituted MgB2
T. Sakuntala, A. Bharathi, S. K. Deb +3
Room temperature Raman scattering measurements have been carried out on well characterized samples of MgB2-xCx. The Raman line corresponding to the E2g phonon mode shows progressiv…
Raman Studies in MgB2-xCx
T. Sakuntala, S. K. Deb, A. Bharathi +3
Raman scattering measurements have been carried out in MgB2-xCx for x=0.0 -0.30. The broad Raman band around 600cm-1 range, which corresponds to the E2g mode in MgB2 is seen to nar…
Tuning of the superconducting and ferromagnetic transitions by Cu doping for Ru in GdSr2RuCu2O8
J. Janaki, T. Geetha Kumary, R. Nagarajan +5
In order to explore the possibility of tuning superconducting and ferromagnetic transitions by Cu doping (for Ru) in GdSr2RuCu2O8, we have carried out synthesis and characterizatio…
Crystal structure, superconductivity and magnetic properties of the superconducting ferromagnets Gd1.4-xDyxCe0.6Sr2RuCu2O10 (x=0 - 0.6)
S. Kalavathi, J. Janaki, G. V. N. Rao +2
The structural, electrical and magnetic properties of the superconducting ferromagnets, Gd1.4-xDyxCe0.6Sr2RuCu2O10 (x=0-0.6) are systematically investigated as a function of Dy dop…
