Magnetic field dependence of superconducting energy gaps in YNi2B2C: Evidence of multiband superconductivity
S Mukhopadhyay, Goutam Sheet, P Raychaudhuri +1
We present results of in field directional point contact spectroscopy (DPCS) study in the quaternary borocarbide superconductor YNi2B2C, which is characterized by a highly anisotro…
Size dependence of the Tc and the superconducting energy gap in nanocrystalline thin films of Nb
Sangita Bose, Pratap Raychaudhuri, Rajarshi Banerjee +2
In nanocrystalline Nb films, the superconducting Tc decreases with a reduction in the average particle size below 20nm. We correlate the decrease in Tc with a reduction in the supe…
Anomalous bias dependence of tunnel magnetoresistance in a magnetic tunnel junction
Soumik Mukhopadhyay, I. Das, S. P. Pai +1
We have fabricated a spin-polarized tunneling device based on half metallic manganites incorporating as insulating barrier. An anomalous bias dependence of tunnel…
Evidence of gap anisotropy in superconducting YNi2B2C using directional point contact spectroscopy
P. Raychaudhuri, D. Jaiswal-Nagar, Goutam Sheet +2
We present a study of the anisotropy in the superconducting energy gap in a single crystal of YNi2B2C (Tc~14.6K) using directional point contact spectroscopy. The superconducting e…
