The different development of the anisotropic upper critical field in MgB2 by aluminum and carbon doping
M. Angst, S. L. Bud'ko, R. H. T. Wilke +1
The temperature dependence of the upper critical field, Hc2, for both field directions in partially substituted polycrystalline MgB2 was determined. Whereas the suppression of Tc i…
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…
Strongly enhancend anisotropic upper critical field in carbon substituted MgB2: impact of Fermi surface changes
R. Puzniak, M. Angst, A. Szewczyk +3
The upper critical field Hc2||c(0) of 85 kOe in Mg(B0.94C0.06)2 single crystals, determined from torque measurements, is more than twice as large as that one of 31 kOe in unsubstit…
