Polarization and driving force analysis of coherent optical shear phonons in graphite
Christian Gerbig, Silvio Morgenstern, Ahmed S. Hassanien +4
Coherent optical phonons in the degenerate inter-layer shear mode of graphite launched by femtosecond laser pulses were investigated using ultrafast electron diffraction. The colle…
Pausing ultrafast melting by timed multiple femtosecond-laser pulses
Tobias Zier, Eeuwe S. Zijlstra, Martin E. Garcia +1
An intense femtosecond-laser excitation of a solid induces highly nonthermal conditions. In materials like silicon, laser-induced bond-softening leads to a highly incoherent ionic…
A new method for microscale cyclic crack growth characterization from notched microcantilevers and application to single crystalline tungsten and a metallic glass
S. Gabel, B. Merle, E. Bitzek +1
The lifetime of most metals is limited by cyclic loads, ending in fatigue failure. The progressive growth of cracks ends up in catastrophic failure. An advanced method is presented…
Polycrystalline exchange-biased bilayers: magnetically effective vs. structural antiferromagnetic grain volume distribution
Maximilian Merkel, Meike Reginka, Rico Huhnstock +1
The magnetic characteristics of polycrystalline exchange-biased antiferromagnet/ferromagnet-bilayers are determined by a complex interplay of parameters, describing structural and…
Stochastic aspects of crack deflection and crack path prediction in short fiber reinforced polymer matrix composites
Andreas Ricoeur, Felix Lindner, Konstantin Zarjov
Owing to the production process, short fiber reinforced composites exhibit a pronounced anisotropy of both elastic properties and crack growth resistance. In particular the latter…
Probing the energy conversion pathways between light, carriers and lattice in real time with attosecond core-level spectroscopy
T. P. H. Sidiropoulos, N. Di Palo, D. E. Rivas +16
Detection of the energy conversion pathways, between photons, charge carriers, and the lattice is of fundamental importance to understand fundamental physics and to advance materia…
Correction of Density-Functional-Theory based polynomial interatomic potentials to reproduce experimental melting properties
Bernd Bauerhenne, Martin E. Garcia
Recently, we developed a method to construct polynomial interatomic potentials from ab-initio calculations in order to accurately describe laser excited solids [PRL 124, 085501 (20…
Magnetic domains without domain walls: a unique effect of He+ ion bombardment in ferrimagnetic Co/Tb multilayers
Łukasz Frąckowiak, Piotr Kuświk, Gabriel David Chaves-O'Flynn +6
We show that it is possible to engineer magnetic multi-domain configurations without domain walls in a prototypical rare earth/transition metal ferrimagnet using keV He+ ion bombar…
Self-learning analytical interatomic potential describing laser-excited silicon
Bernd Bauerhenne, Vladimir P. Lipp, Tobias Zier +2
We develop an electronic-temperature dependent interatomic potential for unexcited and laser-excited silicon. The potential is designed to reproduce ab initio molec…
Wavelength-dependent reflectivity changes on gold at elevated electronic temperatures
A. Blumenstein, E. S. Zijlstra, D. S. Ivanov +7
Upon the excitation by an ultrashort laser pulse the conditions in a material can drastically change, altering its optical properties and therefore the relative amount of absorbed…
Quantitative analysis of the influence of keV He ion bombardment on exchange bias layer systems
Nicolas David Müglich, Gerhard Götz, Alexander Gaul +4
The mechanism of ion bombardment induced magnetic patterning of exchange bias layer systems for creating engineered magnetic stray field landscapes is still unclear. We compare res…
Grain size correlated rotatable magnetic anisotropy in polycrystalline exchange bias systems
Nicolas David Müglich, Gerhard Götz, Alexander Gaul +4
Angular resolved measurements of the exchange bias field and the coercive field are a powerful tool to distinguish between different competing magnetic anisotropies in polycrystall…
Atomistic-continuum modeling of short laser pulse melting of Si targets
V. P. Lipp, B. Rethfeld, M. E. Garcia +1
We present an atomistic-continuum model to simulate ultrashort laser-induced melting processes in semiconductor solids on the example of silicon. The kinetics of transient non-equi…

Junais Habeeb Mokkath, G. M. Pastor
The structural, electronic and magnetic properties of small clusters having atoms are studied in the framework of a generalized-gradient ap…
Elementary transitions and magnetic correlations in two-dimensional disordered nanoparticle ensembles
G. M. Pastor, P. J. Jensen
The magnetic relaxation processes in disordered two-dimensional ensembles of dipole-coupled magnetic nanoparticles are theoretically investigated by performing numerical simulation…
Tailoring the Magnetic Anisotropy in CoRh Nanoalloys: Experiment and Theory
M. Muñoz-Navia, J. Dorantes-Dávila, D. Zitoun +5
The magnetic moments and magnetic anisotropy energy (MAE) of CoRh alloy nanoparticles are determined experimentally and theoretically. Non-trivial correlations between chemical ord…
Hyper-domains in exchange bias micro-stripe pattern
K. Theis-Broehl, A. Westphalen, H. Zabel +9
A combination of experimental techniques, e.g. vector-MOKE magnetometry, Kerr microscopy and polarized neutron reflectometry, was applied to study the field induced evolution of th…

Mario De Menech, Ulf Saalmann, Martin E. Garcia
We present a detailed theoretical study of scanning tunneling imaging and spectroscopy of \Csixty on silver and gold surfaces, motivated by the recent experiments and discussion by…
Concept of deterministic single ion doping with sub-nm spatial resolution
J. Meijer, T. Vogel, B. Burchard +9
We propose a method for deterministic implantation of single atoms into solids which relies on a linear ion trap as an ion source. Our approach allows a deterministic control of th…
Hole dynamics in noble metals
I. Campillo, A. Rubio, J. M. Pitarke +2
We present a detailed analysis of hole dynamics in noble metals (Cu and Au), by means of first-principles many-body calculations. While holes in a free-electron gas are known to li…
