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…
Local magnetization nucleated by non-magnetic impurities in Fe-based superconductors
Maria N. Gastiasoro, Brian M. Andersen
We study impurity-induced magnetic order within a five-band Hubbard model relevant to the normal paramagnetic phase of iron-based superconductors. The existence of the local magnet…
Effects of Lifshitz Transition on Charge Transport in Magnetic Phases of Fe-Based Superconductors
Y. Wang, Maria N. Gastiasoro, Brian M. Andersen +5
The unusual temperature dependence of the resistivity and its in-plane anisotropy observed in the Fe-based superconducting materials, particularly Ba(FeCo)As, h…
Emergent defect states as a source of resistivity anisotropy in the nematic phase of iron pnictides
Maria N. Gastiasoro, I. Paul, Y. Wang +2
We consider the role of potential scatterers in the nematic phase of Fe-based superconductors above the transition temperature to the (pi,0) magnetic state but below the orthorhomb…
Enhancing magnetic stripe order in iron pnictides by RKKY exchange interactions
Maria N. Gastiasoro, Brian M. Andersen
Recent experimental studies have revealed several unexpected properties of Mn-doped BaFe2As2. These include extension of the stripe-like magnetic (pi,0) phase to high temperatures…
