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…

Point-contact study of gap amplitude and symmetry in RuSr_2GdCu_2O_8
G. A. Ummarino, A. Calzolari, D. Daghero +4
We present the results of point-contact spectroscopy measurements in polycrystalline RuSr_2GdCu_2O_8 samples previously characterized from both the structural and the electrical po…
