Magnetic structure and magnon dispersion in LaSrFeO
N. Qureshi, H. Ulbrich, Y. Sidis +2
We present elastic and inelastic neutron scattering data on LaSrFeO. We confirm the known magnetic structure with the magnetic moments lying in the tetragonal basal plane, but…
Neutron scattering studies on stripe phases in non-cuprate materials
Holger Ulbrich, Markus Braden
Several non-cuprates layered transition-metal oxides exhibit clear evidence for stripe ordering of charges and magnetic moments. Therefore, stripe order should be considered as the…
Hourglass dispersion in overdoped single-layered manganites
H. Ulbrich, P. Steffens, D. Lamago +2
The excitation spectrum in single-layered Nd(0.33)Sr(1.67)MnO4 and Pr(0.33)Ca(1.67)MnO4 resembles the hourglass-like excitation dispersion seen in various cuprates superconductors.…
Spin-wave excitations in the ferromagnetic-metallic and in the charge, orbital and spin ordered states in NdSrMnO with x0.5
H. Ulbrich, F. Krüger, A. A. Nugroho +3
Inelastic neutron scattering experiments have been performed on single crystals of NdSrMnO with x0.5. Colossal magnetoresistance (CMR) in the manganite…
Evidence for charge orbital and spin stripe order in an overdoped manganite
H. Ulbrich, D. Senff, P. Steffens +5
We present diffraction data on a single-layered manganite La(0.42)Sr(1.58)MnO4 with hole doping (x>0.5). Overdoped La(0.42)Sr(1.58)MnO4 exhibits a complex ordering of charges, orbi…
