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…
A new approach for improving global critical current density in Fe(Se0.5Te0.5) polycrystalline materials
A. Palenzona, A. Sala, C. Bernini +13
A novel method to prepare bulk Fe(Se0.5Te0.5) samples is presented, based on a melting process and a subsequent annealing treatment. With respect to the standard sintering techniqu…
Effect of external pressure on the magnetic properties of LnFeAsO (Ln = La, Ce, Pr, Sm)
Roberto De Renzi, Pietro Bonfà, Marcello Mazzani +10
We investigate the effect of external pressure on magnetic order in undoped LnFeAsO (Ln = La, Ce, Pr, La) by using muon-spin relaxation measurements and ab-initio calculations. Bot…
Magnetic properties of spin diluted iron pnictides from muSR and NMR in LaFe1-xRuxAsO
Pietro Bonfà, Pietro Carretta, Samuele Sanna +7
The effect of isoelectronic substitutions on the microscopic properties of LaFe1-xRuxAsO, for 0< x< 0.8, has been investigated by means of muSR and 139La NMR. It was found that Ru…
Long- to short-range magnetic order in fluorine-doped CeFeAsO
T. Shiroka, G. Lamura, S. Sanna +13
The evolution of the antiferromagnetic order parameter in CeFeAsO_{1-x}F_{x} as a function of the fluorine content x was investigated primarily via zero-field muon-spin spectroscop…
