Tunable and Persistent Macroscopic Polarization in Nominally Centrosymmetric Defective Oxides
D. -S. Park, N. Pryds, N. Gauquelin +8
Introducing symmetry breaking in materials enables the emergence of functionalities. This can be microscopically and macroscopically driven by applying external stimuli such as mec…
Improved precision and accuracy of electron energy-loss spectroscopy quantification via fine structure fitting with constrained optimization
Daen Jannis, Wouter Van den Broek, Zezhong Zhang +2
By working out the Bethe sum rule, a boundary condition that takes the form of a linear equality is derived for the fine structure observed in ionization edges present in electron…
Relativistic EELS scattering cross-sections for microanalysis based on Dirac solutions
Zezhong Zhang, Ivan Lobato, Hamish Brown +5
The rich information of electron energy-loss spectroscopy (EELS) comes from the complex inelastic scattering process whereby fast electrons transfer energy and momentum to atoms, e…
Imaging the suppression of ferromagnetism in LaMnO by metallic overlayers
Bart Folkers, Thies Jansen, Thijs J. Roskamp +7
LaMnO (LMO) thin films epitaxially grown on SrTiO (STO) usually exhibit ferromagnetism above a critical layer thickness. We report the use of scanning SQUID microscopy (SSM…
Convexity constraints on linear background models for electron energy-loss spectra
Wouter Van den Broek, Daen Jannis, Jo Verbeeck
In this paper convexity constraints are derived for a background model of electron energy loss spectra (EELS) that is linear in the fitting parameters. The model outperforms a powe…
Pattern Formation by Electric-field Quench in Mott Crystal
Nicolas Gauquelin, Filomena Forte, Daen Jannis +10
The control of Mott phase is intertwined with the spatial reorganization of the electronic states. Out-of-equilibrium driving forces typically lead to electronic patterns that are…
