The onset of magnetism peaked around x=1/4 in optimally electron-doped LnFe(1-x)Ru(x)AsO(1-y)F(y) (Ln = La, Nd or Sm) superconductors
S. Sanna, P. Carretta, R. De Renzi +7
The appearance of static magnetism, nanoscopically coexisting with superconductivity, is shown to be a general feature of optimally electron-doped LnFe(1-x)Ru(x)AsO(1-y)F(y) superc…
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…
Phase diagram of low-dimensional antiferromagnets with competing order parameters: A Ginzburg-Landau-theory approach
V. N. Glazkov, F. Casola, H. -R. Ott +1
We present a detailed analysis of the phase diagram of antiferromagnets with competing exchange-driven and field-induced order parameters. By using the quasi-1D antiferromagnet BaC…
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…
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…
