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…
Coexistence of superconductivity and itinerant ferromagnetism in Sr0.5Ce0.5FBiS2-xSex (x = 0.5 and 1.0), the first non-U material with Tc < TFM
Gohil S. Thakur, G. Fuchs, K. Nenkov +4
We have carried out detailed magnetic and transport studies of the new Sr0.5Ce0.5FBiS2-xSex (x = 0.5, 1) superconductors derived by doping Se in Sr0.5Ce0.5FBiS2. Se-doping produces…
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…
Superconductivity in La1-xSmxO0.5F0.5BiS2 (x = 0.2, 0.8) under hydrostatic pressure
G. Kalai Selvan, Gohil Thakur, K. Manikandan +5
We have investigated the pressure effect on the newly discovered samarium doped La1-xSmxO0.5F0.5BiS2 superconductors. More than threefold increase in Tc (10.3 K) is observed with e…
Pressure enhanced superconductivity at 10 K in La doped EuBiS2F
Gohil S. Thakur, Rajveer Jha, Zeba Haque +3
Polycrystalline Eu0.5La0.5BiS2F was synthesized by solid state reaction which crystallizes in the tetragonal CeOBiS2 structure (P4/nmm). We report here enhancement of Tc to 2.2 K i…
CuFeAs: A New Member in the 111-Family of Iron-Pnictides
Gohil S Thakur, Zeba Haque, L C Gupta +1
We have synthesized CuFeAs, a new iron-pnictide compound with a layered tetragonal Cu2Sb type structure (space group P4/nmm: a = b = 3.7442(2) Å and c = 5.8925(4) Å) that is identi…
