Superconducting performance of ex-situ SiC-doped MgB2 mono-filamentary tapes
Gennaro Romano, Arpita Vajpayee, Maurizio Vignolo +2
We report on the superconducting performance of the ex-situ SiC doped MgB2 monofilamentary tapes. Polycrystalline powders of MgB2 doped with 5 and 10 wt% SiC were synthesized by co…
Physical property and electronic structure characterization of bulk superconducting Bi3Ni
Jagdish Kumar, Anuj Kumar, Arpita Vajpayee +5
We report the experimental and theoretical study on magnetic nature of Bi3Ni system. The structure is found to be orthorhombic (Pnma) with lattice parameters a = 8.879Å b = 4.0998Å…
Comparative experimental and Density Functional Theory (DFT) study of the physical properties of MgB2 and AlB2
Devina Sharma, Jagdish Kumar, Arpita Vajpayee +3
In present study, we report an inter-comparison of various physical and electronic properties of MgB2 and AlB2. Interestingly, the sign of S(T) is +ve for MgB2 the same is -ve for…
Effect of synthesis temperature on superconducting properties of n-SiC added bulk MgB2 superconductor
Arpita Vajpayee, R. Jha, A. K. Srivastava +4
We study the effect of synthesis temperature on the phase formation in nano(n)-SiC added bulk MgB2 superconductor. In particular we study: lattice parameters, amount of carbon (C)…
Induction of superconductivity by sulphur doping in FeTe system and post effect of low temperature oxygen annealing
V. P. S. Awana, Anand Pal, Arpita Vajpayee +2
Here, we report the synthesis and characterization of sulphur-substituted iron telluride i.e. FeTe1-xSx; (x = 0-30 %) system and study the impact of low temperature oxygen (O2) ann…
Superconductivity in SmFe1-xCoxAsO (x = 0.0 to 0.30)
V. P. S. Awana, Anand Pal, Arpita Vajpayee +7
We report synthesis, structural details and magnetization of SmFe1-xCoxAsO with x ranging from 0.0 to 0.30. It is found that Co substitutes fully at Fe site in SmFeAsO in an iso-st…
