Automating the analysis of micron-scale synchrotron diffraction data on inhomogeneous polycrystalline samples: a solid oxide electrolysis cell case study
Liam A. V. Nagle-Cocco, Christopher A. Crain, Michael J. Dzara +6
A novel approach to post mortem characterisation of electrochemical and photovoltaic devices is spatially-resolved diffraction using a hyper-focused, micron-width x-ray beam to exa…
Composition-dependent Thin-film Synthesis of Layered Ternary Iron Nitrides FeMN2 (M = W, Mo)
Baptiste Julien, Liam A. V. Nagle-Cocco, Yuwei Yang +3
Ternary transition-metal nitrides with layered crystal structures host anisotropic bonding and reduced dimensionality that may enable unconventional electronic and magnetic behavio…
Revisiting Jahn--Teller Transitions in Correlated Oxides with Monte Carlo Modeling
Liam A. V. Nagle-Cocco, Andrew L. Goodwin, Clare P. Grey +1
Jahn--Teller (JT) distortions are a key driver of physical properties in many correlated oxide materials. Cooperative JT distortions, in which long-range orbital order reduces the…
Incommensurate magnetic modulation in K-rich cryptomelane, KMnO ()
Liam A. V. Nagle-Cocco, Joshua D. Bocarsly, Krishnakanth Sada +9
Cryptomelane is a hollandite-like material consisting of K cations in an -MnO tunnel-like crystallographic motif. A sample with stoichiometry KMnO$_{16…
Thin-Film Stabilization and Magnetism of η-Carbide Type Iron Nitrides
Baptiste Julien, Abrar Rauf, Liam A. V. Nagle-Cocco +4
Transition-metal nitrides in η-carbide type structures exhibit unusual bonding motifs and proximity to magnetic instabilities. Yet they remain unexplored in thin-film form due to…
Orientational Disorder of NH in Hexammine Magnesium Borohydride
Liam A. V. Nagle-Cocco, Andreas Schneemann, Kevin H. Stone +3
Hexammine magnesium borohydride, Mg(NH)(BH), consists of adducted NH molecules locked in a matrix of Mg cations and borohydride anions. It is a candidate materi…
