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…
Persistence of slow fluctuations in the overdoped regime of Ba(Fe1-xRhx)2As2 superconductors
L. Bossoni, M. Moroni, M. H. Julien +5
We present nuclear magnetic resonance evidence that very slow ( MHz) spin fluctuations persist into the overdoped regime of Ba(FeRh)As superconductors…
Enhancement of low-frequency fluctuations and superconductivity breakdown in Mn-doped LaYFeAsOF superconductors
F. Hammerath, M. Moroni, L. Bossoni +9
F NMR measurements in optimally electron-doped LaYFeMnAsOF superconductors are presented. In these materials the effect of Mn d…
The poisoning effect of Mn in LaFe(1-x)Mn(x)AsO(0.89)F(0.11): unveiling a quantum critical point in the phase diagram of iron-based superconductors
F. Hammerath, P. Bonfá, S. Sanna +5
A superconducting-to-magnetic transition is reported for LaFeMnAsOF where a per thousand amount of Mn impurities is dispersed. By employing local spec…
Evidence of unconventional low-frequency dynamics in the normal phase of Ba(Fe1-xRhx)2As2 iron-based supercondutors
L. Bossoni, P. Carretta, W. P. Halperin +4
This work presents 75As NMR spin echo decay rate (1/T2) measurements in Ba(Fe1-xRhx)2As2 superconductors, for 0.041 < x < 0.094. It is shown that 1/T2 increases upon cooling, in th…
