Anomalous field evolution of the mixed-state linewidth in the second superconducting dome of LaFeAsO ()
Rustem Khasanov, Pierre Dalmas de Réotier, Samuele Sanna +9
We report a transverse-field muon-spin rotation/relaxation (SR) study of the internal-field distribution in the mixed state of LaFeAsOF and LaFeAsOH$_…
Fast recovery of the pristine magnetic and structural phases in superconducting LaFeAsOF by Mn/Fe substitution
S. Sanna, P. Carretta, M. Moroni +5
We report on an experimental study of the effect of Mn impurities in the optimally doped LaFeAsOF compound. The results show that a very tiny amount of Mn, of the…
Effect of proton irradiation on the normal state low-energy excitations of Ba(FeRh)As superconductors
M. Moroni, L. Gozzelino, G. Ghigo +4
We present a \asnmr Nuclear Magnetic Resonance (NMR) and resistivity study of the effect of 5.5 MeV proton irradiation on the optimal electron doped ( 0.068) and overdoped ($x=…
Role of magnetic dopants in the phase diagram of Sm1111 pnictides: The Mn case
G. Lamura, T. Shiroka, S. Bordignon +12
The deliberate insertion of magnetic Mn dopants in the Fe sites of the optimally-doped SmFeAsO0.88-F0.12 iron-based superconductor can modify in a controlled way its electronic pro…
Fast recovery of the stripe magnetic order by Mn/Fe substitution in F-doped LaFeAsO superconductors
M. Moroni, P. Carretta, G. Allodi +8
As Nuclear Magnetic (NMR) and Quadrupolar (NQR) Resonance were used, together with Mössbauer spectroscopy, to investigate the magnetic state induced by Mn for Fe substitutio…
Superconductivity emerging from an electronic phase separation in the charge ordered phase of RbFeAs
E. Civardi, M. Moroni, M. Babij +2
As, Rb and Rb nuclear quadrupole resonance (NQR) and Rb nuclear magnetic resonance (NMR) measurements in RbFeAs iron-based superconductor are pr…
