Effects of isoelectronic Ru substitution at the Fe site on the energy gaps of optimally F-doped SmFeAsO
D. Daghero, M. Tortello, G. A. Ummarino +5
We studied the effects of isoelectronic Ru substitution at the Fe site on the energy gaps of optimally F-doped SmFeAsO by means of point-contact Andreev reflection spectroscopy. Th…
Phase separation at the magnetic-superconducting transition in LaYFeAsOF
G. Prando, S. Sanna, G. Lamura +7
In this paper we report a detailed SR and {}F-NMR study of the LaYFeAsOF class of materials. Here, the diamagnetic LaY sub…
Evidence for electromagnetic granularity in polycrystalline Sm1111 iron-pnictides with enhanced phase purity
A. Yamamoto, J. Jiang, F. Kametani +7
We prepared polycrystalline SmFeAsO1-xFx (Sm1111) bulk samples by sintering and hot isostatic pressing (HIP) in order to study the effects of phase purity and relative density on t…
Intrinsic ferromagnetic impurity phases in SmFeAsO1-xFx detected by muSR
S. Sanna, R. De Renzi, G. Lamura +6
We report about muSR measurements on SmFeAsO1-xFx which helped us to identify the signature of diluted ferromagnetic inclusions, ubiquitous in the iron pnictides. These impurities…
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…
