CeMnNi4: A soft ferromagnet with a high degree of transport spin polarization
Surjeet Singh, Goutam Sheet, Pratap Raychaudhuri +1
In this letter we introduce a new soft ferromagnetic compound, i.e. CeMnNi4, which exhibits a large moment (~4.95mu_B/Mn) and high degree of spin polarization. The system has a fer…
Comment on "Spectroscopic Evidence for Multiple Order Parameters in the Heavy Fermion Superconductor CeCoIn5"
Goutam Sheet, Pratap Raychaudhuri
This is a comment on recent paper by Rourke et al. titled "Spectroscopic Evidence for Multiple Order Parameters in the Heavy Fermion Superconductor CeCoIn5" (cond-mat/0409562v1 22…
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…
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…
The role of critical current on point contact Andreev Reflection spectrum between a normal metal and a superconductor
G. Sheet, S. Mukhopadhyay, P. Raychaudhuri
The point contact spectrum between a normal metal and a superconductor often shows unexpected sharp dips in the conductance at voltage values larger than the superconducting energy…
