Electron-Phonon Mediated Superconductivity in 1T MoS2 and Effect of Pressure on the Same
Jagdish Kumar, Harkirat Singh
Density functional theory (DFT) based ab-initio calculations of electronic, phononic, and superconducting properties of 1T MoS2 are reported. The phonon dispersions are computed wi…
Enhanced superconducting performance of melt quenched Bi2Sr2CaCu2O8 (Bi-2212) superconductor
Jagdish Kumar, Devina Sharma, P. K. Ahluwalia +1
We scrutinize the enhanced superconducting performance of melt quench Bismuth based Bi2Sr2CaCu2O8 (Bi-2212) superconductor. The superconducting properties of melt quenched Bi-2212…
Chalcogen Height Dependence of Magnetism and Fermiology in FeTe_xSe_{1-x}
Jagdish Kumar, S. Auluck, P. K. Ahluwalia +1
FeTexSe1-x (x=0, 0.25, 0.50, 0.75 and 1) system has been studied using density functional theory. Our results show that for FeSe, LDA seems better approximation in terms of magnitu…
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…
Superconductivity in the vicinity of ferromagnetism in oxygen free perovskite MgCNi3: An experimental and DFT (Density Functional Theory) study
Anuj Kumar, Rajveer Jha, Shiva Kumar +4
We report synthesis, structural, magnetic, specific heat and Density Functional Theory (DFT) studies on MgCNi3 superconductor. Polycrystalline MgCNi3 samples are synthesized throug…
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…
Anomalous heat capacity and X-ray photoelectron spectroscopy of Superconducting FeSe1/2Te1/2
V. P. S. Awana, Govind, Anand Pal +5
The bulk polycrystalline sample FeSe1/2Te1/2 is synthesized by solid state reaction route in an evacuated sealed quartz tube at 750 oC. The presence of superconductivity is confirm…
