Bi2W2O9: a potentially antiferroelectric Aurivillius phase
Hania Djani, Emma. E. McCabe, W. Zhang +5
Ferroelectric tungsten-based Aurivillius oxides are naturally stable superlattice structures, in which A-site deficient perovskite blocks [WnO3n+1]-2 (n = 1, 2, 3, ...) interleave…
Spin interactions and magnetic order in the iron oxychalcogenides BaFe2Q2O
B. D. Coles, A. D. Hillier, F. C. Coomer +3
The ability to tune the iron chalcogenides BaFe2Q3 from Mott insulators, to metals and then superconductors with applied pressure has renewed interest in low-dimensional iron chalc…
Magnetic order and phase transition in the iron oxysulfide La2O2Fe2OS2
Reeya K. Oogarah, Emmanuelle Suard, Emma E. McCabe
The Mott-insulating iron oxychalcogenides exhibit complex magnetic behaviour and we report here a neutron diffraction investigation into the magnetic ordering in La2O2Fe2OS2. This…
The magnetic and electronic properties of Oxyselenides - influence of transition metal ions and lanthanides
C. Stock, E. E. McCabe
Magnetic oxyselenides have been the topic of research for several decades being first of interest in the context of photoconductivity and thermoelectricity owing to their intrinsic…
Magnetism of the Fe and Ce sublattices in CeOFeSe: a combined neutron powder diffraction, inelastic neutron scattering and density functional study
E. E. McCabe, C. Stock, J. L. Bettis +2
The discovery of superconductivity in the 122 iron selenide materials above 30 K necessitates an understanding of the underlying magnetic interactions. We present a combined experi…
Structural and magnetic characterisation of iron oxyselenides Ce2O2Fe2OSe2 and Nd2O2Fe2OSe2
Emma E. McCabe, Andrew S. Wills, Laurent Chapon +2
We present here an investigation of the magnetic ordering in the Mott insulating oxyselenide materials Ln2O2Fe2OSe2 (Ln = Ce, Nd). Neutron powder diffraction data are consistent wi…
Weak spin interactions in Mott insulating La2O2Fe2OSe2
E. E. McCabe, C. Stock, E. E. Rodriguez +3
Identifying and characterizing the parent phases of iron-based superconductors is an important step towards understanding the mechanism for their high temperature superconductivity…
