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…
Temperature and field dependence of thermally activated flux flow resistance in Bi2Sr2CaCu2O8+δ superconductor
Devina Sharma, Ranjan Kumar, V. P. S. Awana
We study the temperature dependence of the resistivity as a function of magnetic field in superconducting transition (Tconset - TcR=0) region for different Bi2Sr2CaCu2O8+δ supercon…
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…
