Tunneling studies in a homogeneously disordered s-wave superconductor: NbN
S. P. Chockalingam, Madhavi Chand, Anand Kamlapure +4
We report the evolution of superconducting properties as a function of disorder in homogeneously disordered epitaxial NbN thin films grown on (100) MgO substrates, studied through…
Effect of Pt doping on the critical temperature and upper critical field in YNi2-xPtxB2C (x=0-0.2)
Sourin Mukhopadhyay, Goutam Sheet, A. K. Nigam +2
We investigate the evolution of superconducting properties by doping non-magnetic impurity in single crystals of YNi2-xPtxB2C (x=0-0.2). With increasing Pt doping the critical temp…
Study of spin fluctuations in Ni3Al using point contact Andreev reflection spectroscopy
Sourin Mukhopadhyay, Sudesh Kumar Dhar, Pratap Raychaudhuri
We report point contact Andreev reflection (PCAR) spectroscopy studies on Ni3Al with composition range (24, 26 and 27 at. % of Al in the solid solution) spanning the ferromagnetic…
Superconducting properties and Hall Effect of epitaxial NbN thin films
S. P. Chockalingam, Madhavi Chand, John Jesudasan +2
We have measured the magnetotransport properties and Hall effect of a series of epitaxial NbN films grown on (100) oriented single crystalline MgO substrate under different conditi…
Non-intrinsic superconductivity in InN epilayers: role of Indium Oxide
Abdul Kadir, Sourin Mukhopadhyay, Tapas Ganguli +5
In recent years there have been reports of anomalous electrical resistivity and the presence of superconductivity in semiconducting InN layers. By a careful correlation of the temp…
Competing effects of surface phonon softening and quantum size effects on the superconducting properties of nanostructured Pb
Sangita Bose, Charudatta Galande, S. P. Chockalingam +3
The superconducting transition temperature (TC) in nanostructured Pb remains nearly constant as the particle size is reduced from 65 to 7nm, below which size the superconductivity…
