An in-situ X-ray and neutron diffraction investigation of Bi-2212 in multifilamentary wires during thermal treatment
Alberto Martinelli, Emilio Bellingeri, Alessandro Leveratto +3
Significant insights for critical current density (Jc) improvement in Bi-2212 super- conductor wires can be obtained by an accurate analysis of the structural and mi- crostructural…
Role of heat and mechanical treatments in the fabrication of superconducting Ba0.6K0.4Fe2As2 ex-situ Powder-In-Tube tapes
A. Malagoli, E. Wiesenmayer, S. Marchner +3
Among the recently discovered Fe-based superconducting compounds, the (K,Ba)Fe2As2 phase is attracting large interest within the scientific community interested in conductor develo…
Exploring the feasibility of Fe(Se,Te) conductors by ex-situ Powder-in-Tube method
M. Palombo, A. Malagoli, M. Pani +4
In this work, the feasibility condition of Powder-In-Tube (PIT) processed wires of Fe(Se,Te) superconductor has been investigated. We faced several technical issues that are extens…
In-situ high energy synchrotron X-ray diffraction investigation of the MgB2 phase formation and MgB2 tapes sintering
Maurizio Vignolo, Gennaro Romano, Davide Nardelli +7
In the present paper we report an in-situ high-energy X-ray diffraction analysis of MgB2 tapes during the preparation process. The experiment was performed in a specifically design…
Evidence for length-dependent wire expansion, filament dedensification and consequent degradation of critical current density in Ag-alloy sheathed Bi-2212 wires
A Malagoli, P J Lee, A K Ghosh +6
It is well known that longer Bi-2212 conductors have significantly lower critical current density (Jc) than shorter ones, and recently it has become clear that a major cause of thi…
Upper critical field and fluctuation conductivity in the critical regime of doped SmFeAsO
I. Pallecchi, C. Fanciulli, M. Tropeano +7
We measure magnetotransport of F doped SmFeAsO samples up to 28T and we extract the upper critical fields, using different criteria. In order to circumvent the problem of criterion…
