Point-Contact Spectroscopy in MgB_2: from Fundamental Physics to Thin-Film Characterization
R. S. Gonnelli, D. Daghero, A. Calzolari +9
In this paper we highlight the advantages of using point-contact spectroscopy (PCS) in multigap superconductors like MgB_2, both as a fundamental research tool and as a non-destruc…
The Magnetic-field Dependence of the Gaps in a Two-band Superconductor: A Point-contact Study of MgB_2 Single Crystals
R. S. Gonnelli, D. Daghero, A. Calzolari +6
We present the results of directional point-contact measurements in MgB_2 single crystals, in magnetic fields up to 9 T parallel to the c axis. By fitting the conductance curves of…
Unusual magnetic field-induced phase transition in the mixed state of superconducting NbSe2
A. V. Sologubenko, I. L. Landau, H. R. Ott +3
The thermal conductivity κin the basal plane of single-crystalline hexagonal NbSe2 has been measured as a function of magnetic field H, oriented both along and perpendicular to the…
Absence of a boron isotope effect in the magnetic penetration depth of MgB
D. Di Castro, M. Angst, D. G. Eshchenko +11
The magnetic penetration depth in polycrystalline MgB for different boron isotopes (B/B) was investigated by transverse field muon spin rotation. No boro…
Ambivalence of the anisotropy of the vortex lattice in an anisotropic type-II superconductor
I. L. Landau, A. V. Sologubenko, H. R. Ott
We present a geometry-based discussion of possible vortex configurations in the mixed state of anisotropic type-II superconductors. It is shown that, if energy considerations assig…
Directional point-contact spectroscopy of MgB2 single crystals in magnetic fields: two-band superconductivity and critical fields
R. S. Gonnelli, D. Daghero, G. A. Ummarino +6
The results of the first directional point-contact measurements in MgB2 single crystals, in the presence of magnetic fields up to 9 T either parallel or perpendicular to the ab pla…
Effects of proton irradiation and ageing on the superconducting properties of single crystalline and polycrystalline MgB2
G. K. Perkins, Y. Bugoslavsky, A . D. Caplin +7
We present magnetisation data on crystalline and polycrystalline MgB2 before and after irradiation with ~1MeV protons. In the virgin crystal the critical current density is below o…
Anisotropic properties of MgB2 by torque magnetometry
M. Angst, D. Di Castro, R. Puzniak +6
Anisotropic properties of superconducting MgB2 obtained by torque magnetometry are compared to theoretical predictions, concentrating on two issues. Firstly, the angular dependence…
Single crystal growth and properties of MgB2 and Mg(B1-xCx)2
S. M. Kazakov, J. Karpinski, J. Jun +4
Single crystals of MgB2 and Mg(B1-xCx)2 have been grown using cubic anvil technique. Tc values vary in a wide range (39-9 K) with carbon content varying from 0 up to 16%. Using SiC…
Determination of the Fermi Surface of MgB by the de Haas-van Alphen effect
A. Carrington, P. J. Meeson, J. R. Cooper +8
We report measurements of the de Haas-van Alphen effect for single crystals of MgB, in magnetic fields up to 32 Tesla. In contrast to our earlier work, dHvA orbits from all fou…
MgB2 and Mg1-xAlxB2 single crystals: high-pressure growth and physical properties
J. Karpinski, S. M. Kazakov, J. Jun +4
Single crystals of MgB2 have been grown with a high-pressure cubic anvil technique. They grow via the peritectic decomposition of the MgNB9 ternary nitride. The crystals are of a s…
