A second superconducting energy gap of Nb_3Sn observed by breakjunction point-contact spectroscopy
M. Marz, W. Goldacker, R. Lortz +1
We report on investigations of the superconducting energy gap of the A15 superconductor Nb_3Sn by point-contact spectroscopy of breakjunctions. The voltage-dependent differential c…
Point-contact spectroscopy in heavy-fermion superconductors
Mikael Fogelström, W. K. Park, L. H. Greene +2
We develop a minimal model to calculate point-contact spectra between a metallic tip and a superconducting heavy-fermion system. We apply our tunneling model to the heavy fermion C…
A Scanning Tunneling Microscope for a Dilution Refrigerator
M. Marz, G. Goll, H. v. Loehneysen
We present the main features of a home-built scanning tunneling microscope that has been attached to the mixing chamber of a dilution refrigerator. It allows scanning tunneling mic…
Specific heat of Nb_3Sn: The case for a second energy gap
V. Guritanu, W. Goldacker, F. Bouquet +4
We present new specific heat data for Nb3Sn, a well-known technically applied superconductor with a critical temperature T_c ~ 18 K, in the temperature range from 1.2 to 200 K in z…
Excess current in superconducting SrRuO
F. Laube, G. Goll, M. Eschrig +2
We present results from point-contact measurements on SrRuO that show a linear dependence of the excess current as a function of temperature and applied magnetic fields ove…
Superconducting energy gap distribution of MgB investigated by point-contact spectroscopy
F. Laube, G. Goll, J. Hagel +3
We performed point-contact spectroscopy on the binary superconductor MgB. The differential conductance shows gap-related structures which vary in width and position from contac…
Spin-triplet superconductivity in SrRuO probed by Andreev reflection
F. Laube, G. Goll, H. v. Löhneysen +2
The superconducting gap function of SrRuO was investigated by means of quasiparticle reflection and transmission at the normal conductor-superconductor interface of SrR…
