Microwave measurements of the high magnetic field vortex motion pinning parameters in NbSn
Andrea Alimenti, Nicola Pompeo, Kostiantyn Torokhtii +4
The high frequency vortex motion in NbSn was analyzed in this work up to 12 T. We used a dielectric loaded resonator tuned at 15 GHz to evaluate the surface impedance of a…
Transport critical current densities and n factors in mono- and multifilamentary MgB2/Fe tapes and wires using fine powders
H. L. Suo, P. Lezza, D. Uglietti +3
Mono- and multifilamentary MgB2/Fe tapes and wires with high transport critical current densities have been prepared using the powder-in-tube (PIT) process. The fabrication details…
AC losses in Bi,Pb(2223) multifilamentary wires with square cross-section
G. Witz, X. -D Su, K. Kwasnitza +1
We have fabricated prototype Bi,Pb(2223)/Ag superconduting multifilamentary wires with a square cross-section. The AC losses of these wires were measured, compared with those of ta…
High-pressure synthesis of pure and doped superconducting MgB2 compounds
P. Toulemonde, N. Musolino, R. Flukiger
Superconducting properties of bulk, dense, pure MgB2 and doped (Mg1-xAx)B2 samples with A = Na, Ca, Cu, Ag, Zn and Al were studied for compositional ranges 0 < x < 0.20. The effect…
Fabrication and transport critical currents of multifilamentary MgB2/Fe wires and tapes
H. L. Suo, C. Beneduce, X. D. Su +1
Multifilamentary MgB2/Fe wires and tapes with high transport critical current densities have been fabricated using a straightforward powder-in-tube (PIT) process. After annealing,…
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…
Transport - and inductive critical current densities in superconducting MgB2
Marc Dhalle, Pierre Toulemonde, Concetta Beneduce +3
The critical current density of four MgB2 samples was measured inductively and for one of them also by transport. Pure phased and dense bulk samples yield a critical current densit…
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 coherent Josephson response in the non-linear ab-plane microwave impedance of single crystals
Z. Zhai, H. Srikanth, S. Sridhar +3
We report novel non-linear phenomena in the -plane microwave impedance of single crystals. The vs. data are well described by the non-linear R…
New features in the microwave response of YBCO crystals: Evidence for a multi-component order parameter
H. Srikanth, Balam A. Willemsen, T. Jacobs +4
New features are reported in precision measurements of the complex microwave conductivity of high quality crystals grown in crucibles. A third p…
