Large transport critical currents in dense Fe- and Ni-clad MgB2 superconducting tapes
HongLi Suo, Concetta Beneduce, Marc Dhalle +3
We report on the preparation of dense monofilamentary MgB2/Ni and MgB2/Fe tapes with high critical current densities. In annealed MgB2/Ni tapes, we obtained transport critical curr…

Experimental evidence for fast cluster formation of chain oxygen vacancies in YBa2Cu3O7-d being at the origin of the fishtail anomaly
Andreas Erb, Alfred A. Manuel, Marc Dhalle +13
We report on three different and complementary measurements, namely magnetisation measurements, positron annihilation spectroscopy and NMR measurements, which give evidence that th…

Observation of d-wave scaling relations in the mixed-state specific heat of YBa2Cu3O7
B. Revaz, J. -Y. Genoud, A. Junod +2
The low temperature specific heat C(B,T) of an YBa2Cu3O7.00 single crystal is measured from 1.2 to 10 K in magnetic fields up to 14 T. The anisotropic component Caniso(T,B)=C(T,B//…
