Magnetism of the Fe2+ and Ce3+ sublattices in Ce2O2FeSe2: A combined neutron powder diffraction, inelastic neutron scattering, and density functional study (2014)
Journal Article
McCabe, E., Stock, C., Bettis Jr., J., Whangbo, M., & Evans, J. (2014). Magnetism of the Fe2+ and Ce3+ sublattices in Ce2O2FeSe2: A combined neutron powder diffraction, inelastic neutron scattering, and density functional study. Physical review B, 90(23), Article 235115. https://doi.org/10.1103/physrevb.90.235115

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 experimental and theoretical investigation of magnetic and semiconducting Ce...

Structural and magnetic characterization of iron oxyselenides Ce2O2Fe2OSe2 and Nd2O2Fe2OSe2 (2014)
Journal Article
McCabe, E., Wills, A., Chapon, L., Manuel, P., & Evans, J. (2014). Structural and magnetic characterization of iron oxyselenides Ce2O2Fe2OSe2 and Nd2O2Fe2OSe2. Physical review B, 90(16), Article 165111. https://doi.org/10.1103/physrevb.90.165111

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 with a noncollinear multi-k ordering on the iron sublattice structure and...

Weak spin interactions in Mott insulating La2O2Fe2OSe2 (2014)
Journal Article
McCabe, E., Stock, C., Rodriguez, E., Wills, A., Taylor, J., & Evans, J. (2014). Weak spin interactions in Mott insulating La2O2Fe2OSe2. Physical review B, 89(10), Article 100402(R). https://doi.org/10.1103/physrevb.89.100402

Identifying and characterizing the parent phases of iron-based superconductors is an important step towards understanding the mechanism for their high-temperature superconductivity. We present an investigation into the magnetic interactions in the Mo... Read More about Weak spin interactions in Mott insulating La2O2Fe2OSe2.
