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…
Spin excitations in the nematic phase and the metallic stripe spin-density wave phase of iron pnictides
M. Kovacic, M. H. Christensen, M. N. Gastiasoro +1
We present a general study of the magnetic excitations within a weak-coupling five-orbital model relevant to itinerant iron pnictides. As a function of enhanced electronic correlat…
Competing superconducting and magnetic order parameters and field-induced magnetism in electron doped Ba(FeCo)As
J. Larsen, B. Mencia Uranga, G. Stieber +6
We have studied the magnetic and superconducting properties of Ba(FeCo)As as a function of temperature and external magnetic field using neutron scatt…
Robustness of the nodal d-wave spectrum to strongly fluctuating competing order
W. A. Atkinson, J. David Bazak, B. M. Andersen
We resolve an existing controversy between, on the one hand, convincing evidence for the existence of competing order in underdoped cuprates, and, on the other hand, spectroscopic…
Modulations of the local pairing interaction near magnetic impurities in d-wave superconductors
A. T. Roemer, S. Graser, P. J. Hirschfeld +1
The spin-fluctuation based pairing mechanism has proven successful in explaining the pairing symmetries due to Fermi surface nesting of both cuprates and iron-based materials. In t…
Signatures of orbital loop currents in the spatially resolved local density of states
W. H. P. Nielsen, W. A. Atkinson, B. M. Andersen
Polarized neutron scattering measurements have suggested that intra-unit cell antiferromagnetism may be associated with the pseudogap phase. Assuming that loop current order is res…
Correlation and disorder-enhanced nematic spin response in superconductors with weakly broken rotational symmetry
Brian M. Andersen, Siegfried Graser, P. J. Hirschfeld
Recent experimental and theoretical studies have highlighted the possible role of a electronic nematic liquid in underdoped cuprate superconductors. We calculate, within a model of…
Modeling a striped pseudogap state
M. Granath, B. M. Andersen
We study the electronic structure within a system of phase-decoupled one-dimensional superconductors coexisting with stripe spin and charge density wave order. This system has a no…
