Measuring the Penetration Depth Anisotropy in MgB using Small-Angle Neutron Scattering
D. Pal, L. DeBeer-Schmitt, T. Bera +7
Using small-angle neutron scattering we have measured the misalignment between an applied field of 4 kOe and the flux-line lattice in MgB, as the field is rotated away from the…
Al substitution in MgB2 crystals: influence on superconducting and structural properties
J. Karpinski, N. D. Zhigadlo, G. Schuck +11
Single crystals of Mg1-xAlxB2 have been grown at a pressure of 30 kbar using the cubic anvil technique. Precipitation free crystals with x < 0.1 were obtained as a result of optimi…
A Point-Contact Study of the Superconducting Gaps in Al-Substituted and C-Substituted MgB_2 Single Crystals
R. S. Gonnelli, D. Daghero, G. A. Ummarino +6
We present the results of directional point-contact spectroscopy in state-of-the-art Mg_{1-x}Al_xB_2 and Mg(B_{1-y}C_{y})_2 single crystals produced at ETH, Zurich. Fitting the con…
Evidence for Single-gap Superconductivity in Mg(B_{1-x}C_x)_2 Single Crystals with x=0.132 from Point-Contact Spectroscopy
R. S. Gonnelli, D. Daghero, A. Calzolari +6
We report the results of the first directional point-contact measurements in Mg(B_{1-x}C_{x})_2 single crystals with 0.047 <= x <= 0.132. The two-gap superconductivity typical of M…
Anisotropy and internal field distribution of MgB2 in the mixed state at low temperatures
M. Angst, D. Di Castro, D. G. Eshchenko +11
Magnetization and muon spin relaxation on MgB2 were measured as a function of field at 2 K. Both indicate an inverse-squared penetration depth strongly decreasing with increasing f…
Carbon substitution in MgB2 single crystals: structural and superconducting properties
S. M. Kazakov, R. Puzniak, K. Rogacki +6
Growth of carbon substituted magnesium diboride Mg(B1-xCx)2 single crystals with 0<x<0.15 is reported and the structural, transport, and magnetization data are presented. The super…
