Pressure-enhanced superconductivity in cage-type quasiskutterudite Sc5Rh6Sn18 single crystal
Govindaraj Lingannan, Boby Joseph, Muthukumaran Sundaramoorthy +3
Sc5Rh6Sn18 with a cage-type quasiskutterudite crystal lattice and type II superconductivity, with superconducting transition temperature Tc = 4.99 K, was investigated under hydrost…
Wohlleben Effect and Emergent Pi junctions in superconducting Boron doped Diamond thin films
L. Govindaraj, S. Arumugam, R. Thiyagarajan +9
Diamond is an excellent band insulator. However, boron (B) doping is known to induce superconductivity. We present two interesting effects in superconducting B doped diamond (BDD)…
Superconductivity in Se-doped new materials EuSr2Bi2S4F4 and Eu2SrBi2S4F4
Zeba Haque, Gohil S. Thakur, Rainer Pöttgen +5
From our powder x ray diffraction pattern, electrical transport and magnetic studies we report the effect of isovalent Se substitution at S sites in the newly discovered systems Eu…
Unusual mixed valence of Eu in two new materials EuSr2Bi2S4F4 and Eu2SrBi2S4F4: Mössbauer and X-ray photoemission Spectroscopy investigations
Zeba Haque, Gohil Singh Thakur, Rangasamy Parthasarathy +9
We have synthesized two new Eu-based compounds, EuSr2Bi2S4F4 and Eu2SrBi2S4F4 which are derivatives of Eu3Bi2S4F4, an intrinsic superconductor with Tc = 1.5 K. They belong to a tet…
Upper critical field, critical current density and activation energy of the new La1-xSmxOF0.5BiS2 (x = 0.2, 0.8) superconductor
G. Kalai Selvan, G. S. Thakur, K. Manikandan +5
Critical current density (Jc), thermal activation energy (U0), and upper critical field (Hc2) of La1-xSmxO0.5F0.5BiS2 (x = 0.2, 0.8) superconductors are investigated from magnetic…
