Strong magnetic pair breaking in Mn substituted MgB_2 single crystals
K. Rogacki, B. Batlogg, J. Karpinski +9
Magnetic ions (Mn) were substituted in MgB_2 single crystals resulting in a strong pair-breaking effect. The superconducting transition temperature, T_c, in Mg_{1-x}Mn_xB_2 has bee…
Superconducting vortex profile from fixed point measurements The Lazy Fisherman tunnelling microscopy method
A. Kohen, T. Cren, Th. Proslier +7
We introduce a mode of operation for studying the vortex phase in superconductors using scanning tunnelling microscopy (STM). While in the conventional STM method, the tip is scann…
de Haas-van Alphen effect investigation of the electronic structure of Al substituted MgB_2
A. Carrington, J. D. Fletcher, J. R. Cooper +7
We report a de Haas-van Alphen (dHvA) study of the electronic structure of Al doped crystals of MgB. We have measured crystals with % Al which have a of 33.6 K,…
Evidence for a smooth superconductor to normal state transition for nonzero applied magnetic field in RbOs2O6
T. Schneider, R. Khasanov, J. Karpinski +2
The effect of the magnetic field on the critical behavior of RbOs2O6 is investigated. We present and analyze magnetization data, revealing remarkable consistency with a magnetic fi…
Intrinsic thermodynamic properties of the pyrochlore superconductor RbOs2O6 extracted by condensation energy analysis
M. Brühwiler, S. M. Kazakov, J. Karpinski +1
We develop a general procedure for the analysis of bulk thermodynamic data of a superconductor for samples containing a metallic non-superconducting second phase. The method is bas…
Temperature dependent anisotropy of the penetration depth and coherence length in MgB$_2
J. D. Fletcher, A. Carrington, O. J. Taylor +2
We report measurements of the temperature dependent anisotropies ( and ) of both the London penetration depth and the upper critical field of MgB. Data for $γ_λ=λ…
