Multi-band conductivity and multi-gap superconductivity in V3Si from optical measurements on films at terahertz frequencies
A. Perucchi, D. Nicoletti, M. Ortolani +13
The possibility of multi-band conductivity and multi-gap superconductivity is explored in oriented V3Si thin films by means of reflectance and transmittance measurements at teraher…
Magnetic characterization of undoped and 15%F doped LaFeAsO and SmFeAsO compounds
M. R. Cimberle, F. Canepa, M. Ferretti +6
In this paper the magnetic behaviour of undoped and 15% F doped SmFeAsO (Sm-1111) and LaFeAsO (La-1111) samples is presented and discussed. Magnetization measurements are not a sim…
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…
Synthesis, crystal structure, microstructure, transport and magnetic properties of SmFeAsO and SmFeAs(O0.93F0.07)
A. Martinelli, M. Ferretti, P. Manfrinetti +7
SmFeAsO and the isostructural superconducting SmFeAs(O0.93F0.07) samples were prepared. Characterization by means of Rietveld refinement of X-ray powder diffraction data, scanning…
Formation and mobility of oxygen vacancies in RuSr2GdCu2O8
F. Cordero, M. Ferretti, M. R. Cimberle +1
Oxygen vacancies are introduced in the RuO2 and possibly CuO2 planes of RuSr2GdCu2O8 by annealing in vacuum above 600 K. The diffusive jumps of the O vacancies are accompanied by a…
Andreev reflection in Au/La_{2-x}Sr_{x}CuO_{4} point-contact junctions: separation between pseudogap and phase-coherence gap
R. S. Gonnelli, A. Calzolari, D. Daghero +4
We made point-contact measurements with Au tips on La_{2-x}Sr_{x}CuO_{4} samples with 0.08 < x < 0.20 to investigate the relationship between superconducting gap and pseudogap. We…
