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…
Magnetic-superconducting phase boundary of SmFeAsOF studied via muon spin rotation: Unified behavior in a pnictide family
S. Sanna, R. De Renzi, G. Lamura +5
We present uSR investigations on SmFeAsO_1-xF_x showing coexistence of magnetic order and superconductivity only in a very narrow F-doping range. The sharp crossover between the tw…
Experimental confirmation of the low B isotope coefficient in MgB2
P. Brotto, M. Tropeano, C. Ferdeghini +4
Recent investigations have shown that the first proposed explanations of the disagreement between experimental and theoretical value of isotope coefficient in MgB2 need to be recon…
