Synthesis, characterization and low temperature studies of iron chalcogenide superconductors
J. Janaki, T. Geetha Kumary, Awadhesh Mani +4
We have synthesized tetragonal iron selenide and telluride superconductors through solid state reaction at 450deg.C and 550deg.C respectively. These synthesis temperatures have bee…
Superconducting Fe(1+delta)Se(1-x)Te(x) thin films: Growth, characterization and properties
T. Geetha Kumary, Dipak Kumar Baisnab, J. Janaki +5
Thin films of Fe(1+delta)Se(1-x)Te(x) (delta ~ 0.18 & x ~ 0.5) have been successfully grown on (100) oriented single crystalline SrTiO3 and LaAlO3 substrates by pulsed laser deposi…
Effect of Mn substitution on the delicate balance between structure and properties of Gd1.4Ce0.6Sr2RuCu2O10
S. Kalavathi, J. Janaki, T. N. Sairam +3
Some new members of a Ruthenocuprate (2212) series have been synthesized by Mn substitution for Ru in Gd1.4Ce0.6Sr2RuCu2O10 . Characterisation by XRD phase analysis followed by Rie…
Structural Behavior of Non-Oxide Perovskite Superconductor MgCNi at Pressures up to 32 GPa
Ravhi S Kumar, A. L. Cornelius, Yongrong Shen +4
We report the pressure dependence of the structural parameters of the non-oxide perovskite superconductor MgCNi up to 32 GPa using a diamond anvil cell and synchrotron x-rays…
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…
