Effect of the chemical pressure on superconductivity and SDW in undoped and 15%F doped La1-yYyFeAsO compounds
M. Tropeano, C. Fanciulli, F. Canepa +7
We present a study concerning the partial substitution of yttrium at the lanthanum site of the undoped LaFeAsO and superconducting LaFeAsO0.85F0.15 compounds. We prepared samples w…
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…
Transport and infrared properties of SmFeAs(O1-xFx): from SDW to superconducting ordering
M. Tropeano, C. Fanciulli, C. Ferdeghini +12
We report measurements of resistivity, magnetoresistivity, Hall effect, Seebeck coefficient, infrared reflectivity of undoped SmFeAsO and lightly doped SmFeAs(O0.93F0.07) oxypnicti…
Effect of grain refinement on enhancing critical current density and upper critical field in undoped MgB2 ex-situ tapes
A. Malagoli, V. Braccini, M. Tropeano +9
Ex-situ Powder-In-Tube MgB2 tapes prepared with ball-milled, undoped powders showed a strong enhancement of the irreversibility field H*, the upper critical field Hc2 and the criti…
Superconducting and thermal properties of ex-situ Glidcop sheathed multifilamentary MgB2 wires
A Malagoli, M Tropeano, V Cubeda +6
In DC and AC practical applications of MgB2 superconducting wires an important role is represented by the material sheath which has to provide, among other things, a suitable elect…
