Theory of momentum-resolved magnon electron energy loss spectra: The case of Yttrium Iron Garnet
Julio A. do Nascimento, Phil J. Hasnip, S. A. Cavill +5
We explore the inelastic spectra of electrons impinging in a magnetic system. The methodology here presented is intended to highlight the charge-dependent interaction of the electr…
Emergent half-metal with mixed structural order in (111)-oriented (LaMnO)|(SrMnO) superlattices
Fabrizio Cossu, Jùlio Alves Do Nascimento, Stuart A. Cavill +3
Using first-principles techniques, we study the structural, magnetic and electronic properties of (111)-oriented (LaMnO)(SrMnO) superlattices of varying…
Confined magnon dispersion in ferromagnetic and antiferromagnetic thin films in a second quantization approach: the case of Fe and NiO
Julio A. do Nascimento, Adam Kerrigan, S. A. Cavill +4
We present a methodology based on the calculation of the inelastic scattering from magnons via the spin scattering function in confined geometries such as thin films using a second…
Direct mapping of electronic orbitals in graphene using electron energy-loss spectroscopy
M. Bugnet, M. Ederer, V. K. Lazarov +4
The spatial distributions of anti-bonding and states in epitaxial graphene multilayers are mapped using electron energy-loss spectroscopy in a scanning transmissi…
Defect-Correlated Skyrmions and Controllable Generation in Perpendicularly Magnetized CoFeB Ultrathin Films
Haihong Yin, Xiangyu Zheng, Junlin Wang +13
Skyrmions have attracted significant interest due to their topological spin structures and fascinating physical features. The skyrmion phase arises in materials with Dzyaloshinskii…
Role of anti-phase boundaries in the formation of magnetic domains in magnetite thin films
Roberto Moreno, Sarah Jenkins, Vlado K. Lazarov +1
Anti-phase boundaries (APBs) are structural defects which have been shown to be responsible for the anomalous magnetic behaviour observed in different nanostructures. Understanding…
The role of faceting and elongation on the magnetic anisotropy of magnetite Fe3O4 nanocrystals
Roberto Moreno, Samuel Poyser, Daniel Meilak +6
Fe3O4 nanoparticles are one of the most promising candidates for biomedical applications such as magnetic hyperthermia and theranostics due to their bio-compatibility, structural s…
Enhancement of intrinsic magnetic damping in defect-free epitaxial Fe3O4 thin films
Xianyang Lu, Lewis J. Atkinson, Balati Kuerbanjiang +10
We have investigated the magnetic damping of precessional spin dynamics in defect-controlled epitaxial grown FeO(111)/Yttria-stabilized Zirconia (YSZ) nanoscale films by al…
Elementary specific spin and orbital moments of ultrathin CoFeB amorphous films on GaAs(100)
Yu Yan, Cong Lu, Hongqing Tu +12
Nanoscale CoFeB amorphous films have been synthesized on GaAs(100) and studied with X-ray magnetic circular dichroism (XMCD) and transmission electron microscopy (TEM). We have fou…
