Journal ArticleDOI
Ferromagnetism in one-dimensional monatomic metal chains.
Pietro Gambardella,A. Dallmeyer,Kalobaran Maiti,M. C. Malagoli,Wolfgang Eberhardt,Klaus Kern,Carlo Carbone,Carlo Carbone +7 more
TL;DR: Evidence is found that the monatomic chains consist of thermally fluctuating segments of ferromagnetically coupled atoms which, below a threshold temperature, evolve into a ferromagnetic long-range-ordered state owing to the presence of anisotropy barriers.
Journal ArticleDOI
Lensless imaging of magnetic nanostructures by X-ray spectro-holography
Stefan Eisebitt,Jan Lüning,William F. Schlotter,M. Lörgen,Olav Hellwig,Wolfgang Eberhardt,Joachim Stöhr +6 more
TL;DR: This work demonstrates a versatile technique for imaging nanostructures, based on the use of resonantly tuned soft X-rays for scattering contrast and the direct Fourier inversion of a holographically formed interference pattern, which is a form of Fourier transform holography and appears scalable to diffraction-limited resolution.
Journal ArticleDOI
Femtosecond modification of electron localization and transfer of angular momentum in nickel.
Christian Stamm,Torsten Kachel,Niko Pontius,Rolf Mitzner,T. Quast,Karsten Holldack,S. Khan,C. Lupulescu,Emad F. Aziz,M. Wietstruk,Hermann A. Dürr,Wolfgang Eberhardt +11 more
TL;DR: It is shown that an efficient novel channel for angular momentum dissipation to the lattice can be opened by femtosecond laser excitation of a ferromagnet, and for the first time, the quenching of spin angular momentum and its transfer toThe lattice with a time constant of 120+/-70 fs is determined unambiguously with X-ray magnetic circular dichroism.
Book ChapterDOI
Angle-resolved photoemission as a tool for the study of surfaces
E. W. Plummer,Wolfgang Eberhardt +1 more
Journal ArticleDOI
Photoemission from mass-selected monodispersed Pt clusters.
TL;DR: Measurements of the valence- and core-level photoemission spectra of mass-selected, monodispersed Pt clusters conclude that such small metal clusters do not yet exhibit metallic character.
