Synthesis and superconductivity of new BiS2 based superconductor PrO0.5F0.5BiS2
Rajveer Jha, Anuj Kumar, Shiva Kumar Singh +1
We report synthesis and superconductivity at 3.7K in PrO0.5F0.5BiS2. The newly discovered material belongs to the layered sulfide based REO0.5F0.5BiS2 compounds having ZrCuSiAs typ…
Superconductivity at 5K in NdO0.5F0.5BiS2
Rajveer Jha, Anuj Kumar, Shiva Kumar Singh +1
We report appearance of superconductivity at 5K in NdO0.5F0.5BiS2 and supplement the discovery [1] of the same in layered sulfide based ZrCuSiAs type compounds. The bulk polycrysta…
Appearance of superconductivity in new BiS2 based layered LaO0.5F0.5BiS2
V. P. S. Awana, Anuj Kumar, Rajveer Jha +5
We report here synthesis, structural, DC magnetization, and transport studies of new BiS2 based layered LaO0.5F0.5BiS2 superconductor [1]. The sample was synthesized by conventiona…
Bulk Superconductivity in Bismuth-oxy-sulfide Bi4O4S3
Shiva Kumar Singh, Anuj Kumar, Bhasker Gahtori +4
Very recent report [1] on observation of superconductivity in Bi4O4S3 could potentially reignite the search for superconductivity in a broad range of layered sulphides. We report h…
High field magneto-transport and magnetization study of Y1-xCaxBa2Cu3O7-δ(x = 0.0-0.25)
N. P. Liyanawaduge, Anuj Kumar, Rajveer Jha +2
We report DC isothermal magnetization, global critical current density (JC), Intra-grain critical current density (JCintra) and resistive upper critical field (Bc2) of polycrystall…
Effect of Boron substitution on the superconductivity of non-oxide perovskite MgCNi3
Anuj Kumar, Rajveer Jha, R. P. Tandon +1
We report synthesis, structural and magnetic (DC and AC) properties of Boron substituted MgCNi3 superconductor. A series of polycrystalline bulk samples Mg1.2C1.6-xBxNi3 (x = 0.0,…
Synthesis and superconductivity of CeNi0.8Bi2: New entrant in superconductivity kitchen?
Anuj Kumar, Shiva Kumar, Rajveer Jha +1
CeNi0.8Bi2 is very recent entrant in superconductivity kitchen [1], and the same seeks reproduction from other groups. We report synthesis, structural details and superconductivity…
Magnetization and Magneto-resistance in Y(Ba1-xSrx)2Cu3O7-δ (x = 0.00 - 0.50) superconductor
N. P. Liyanawaduge, Shiva Kumar Singh, Anuj Kumar +3
Here we present the magnetic properties and upper critical field (BC2) of polycrystalline Y(Ba1-xSrx)2Cu3O7-δ superconductors, which are being determined through detailed ac/dc sus…
