Field tunable three-dimensional magnetic nanotextures in cobalt-nickel nanowires
I. M. Andersen, D. Wolf, L. A. Rodriguez +8
Cylindrical magnetic nanowires with large transversal magnetocrystalline anisotropy have been shown to sustain non-trivial magnetic configurations resulting from the interplay of s…
Maximal Anderson Localization and Suppression of Surface Plasmons in Two-Dimensional Random Au Networks
Johannes Schultz, Karl Hiekel, Pavel Potapov +4
Two-dimensional random metal networks possess unique electrical and optical properties, such as almost total optical transparency and low sheet resistance, which are closely relate…
Hard X-ray photoemission spectroscopy of LaVO/SrTiO: Band alignment and electronic reconstruction
M. Stübinger, J. Gabel, P. Scheiderer +13
The heterostructure consisting of the Mott insulator LaVO and the band insulator SrTiO is considered a promising candidate for future photovoltaic applications. Not only do…
Extraction of physically meaningful endmembers from STEM spectrum-images combining geometrical and statistical approaches
Pavel Potapov, Axel Lubk
This article addresses extraction of physically meaningful information from STEM EELS and EDX spectrum-images using methods of Multivariate Statistical Analysis. The problem is int…
Layered van der Waals topological metals of TaTMTe4 (TM = Ir, Rh, Ru) family
G. Shipunov, B. R. Piening, C. Wuttke +12
Layered van~der~Waals materials of the family TaTMTe (TM=Ir, Rh, Ru) are showing very interesting electronic properties. Here we report the synthesis, crystal growth and struct…
Tailoring Plasmonics of Au@Ag Nanoparticles by Silica Encapsulation
Johannes Schultz, Felizitas Kirner, Pavel Potapov +3
Hybrid metallic nanoparticles encapsulated in oxide shells are currently intensely studied for plasmonic applications in sensing, medicine, catalysis, and photovoltaics. Here, we i…
A Hamiltonian Mechanics Framework for Charge Particle Optics in Straight and Curved Systems
Felix Kern, Jonas Krehl, Arsha Thampi +1
Charged particle optics, the description of particle trajectories in the vicinity of some optical axis, describe the imaging properties of particle optics devices. Here, we present…
Structural Study of a Self-Assembled Gold Mesocrystal Grain by Coherent X-ray Diffraction Imaging
J. Carnis, F. Kirner, D. Lapkin +15
Mesocrystals are nanostructured materials consisting of individual nanocrystals having a preferred crystallographic orientation. On mesoscopic length scales, the properties of meso…
Unveiling the three-dimensional spin texture of skyrmion tubes
Daniel Wolf, Sebastian Schneider, Ulrich K. Rößler +6
Magnetic skyrmions are stable topological solitons with complex non-coplanar spin structures. Their nanoscopic size and the low electric currents required to initiate and control t…
