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…
Magnetic properties of undoped and 15%F doped SmFeAsO compounds
R. Cimberle, C. Ferdeghini, F. Canepa +5
In this paper the magnetic behaviour of SmFeAsO and SmFeAs(O0.85F0.15) samples is presented and discussed. Molar susceptibility of SmFeAsO exhibits a local peak at T around 140K du…
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…
Very high upper critical fields in MgB2 produced by selective tuning of impurity scattering
A. Gurevich, S. Patnaik, V. Braccini +16
We report a significant enhancement of the upper critical field of different samples alloyed with nonmagnetic impurities. By studying films and bulk polycrystals w…
Thermal conductivity of MgB in the superconducting state
M. Putti, V. Braccini, E. Galleani d'Agliano +5
We present thermal conductivity measurements on very pure and dense bulk samples, as indicated by residual resistivity values as low as 0.5 mW cm and thermal conductivity values hi…
