Specific-heat measurements of superconducting NbS2 single crystal in an external magnetic field: Study on the energy gap structure
J. Kacmarcik, Z. Pribulova, C. Marcenat +4
The heat capacity of a 2H-NbS2 single crystal has been measured by a highly sensitive ac technique down to 0.6 K and in magnetic fields up to 14 T. At very low temperatures data sh…
Scanning tunneling spectroscopy with superconducting tips of Al
I. Guillamon, H. Suderow, S. Vieira +1
We present Scanning Tunneling Spectroscopy measurements at 0.1 K using tips made of Al. At zero field, the atomic lattice and charge density wave of 2HNbSe2 are observed, and under…
Penetration depth study of superconducting gap structure of 2\textit{H}-NbSe
J. D. Fletcher, A. Carrington, P. Diener +5
We report measurements of the temperature dependence of both in-plane and out-of-plane penetration depths ( and respectively) in 2\textit{H}-NbSe. Measurements wer…
Comment on "Precision global measurements of London penetration depth in FeTeSe"
T. Klein, P. Rodiere, C. Marcenat
Cho et al. [Phys. Rev. B, 84, 174502 (2011)] have reported on the temperature dependence of the London penetration depth deduced from Tunnel Diode Oscillator (TDO) measurements in…
Scanning microscopies of superconductors at very low temperatures
V. Crespo, A. Maldonado, J. A. Galvis +7
We discuss basics of scanning tunneling microscopy and spectroscopy (STM/S) of the superconducting state with normal and superconducting tips. We present a new method to measure th…
Superconducting density of states and vortex cores of 2H-NbS2
I. Guillamon, H. Suderow, S. Vieira +3
Scanning tunneling microscopy and spectroscopy (STM/S) measurements in the superconducting dichalcogenide 2H-NbS2 show a peculiar superconducting density of states with two well de…
