Direct observation of half-metallicity in the Heusler compound Co2MnSi
Martin Jourdan,Jan Minár,Jürgen Braun,Alexander Kronenberg,Stanislav Chadov,Benjamin Balke,Andrei Gloskovskii,M. Kolbe,Hans-Joachim Elmers,Gerd Schönhense,Hubert Ebert,Claudia Felser,Mathias Kläui +12 more
TL;DR: This work investigates epitaxial thin films of the compound Co2MnSi in situ by ultraviolet-photoemission spectroscopy, taking advantage of a novel multi-channel spin filter and shows a highly spin polarized bulk-like surface resonance ingrained in a half metallic bulk band structure.
Monitoring surface resonances on Co2MnSi (100) by spin-resolved photoelectron spectroscopy

TL;DR: In this paper, the surface resonance is embedded in the bulk continuum with a strong coupling to the majority bulk states, and the resonance behaves very bulk-like, as it extends over the first six atomic layers of the corresponding (001)-surface.

TL;DR: A novel concept of multichannel spin-polarization analysis is reported that provides a stunning increase in efficiency by 4 orders of magnitude and was demonstrated in a setup using a hemispherical electron energy analyzer.
Imaging spin filter for electrons based on specular reflection from iridium (001)
D. Kutnyakhov,Pavel Lushchyk,Andreas Fognini,D. Perriard,M. Kolbe,Katerina Medjanik,E. Fedchenko,Sergej A. Nepijko,Hans-Joachim Elmers,Gerard Salvatella,C. Stieger,Rafael Gort,T. Bahler,T. Michlmayer,Yves Acremann,Andreas Vaterlaus,F. Giebels,H. Gollisch,R. Feder,Christian Tusche,A. Krasyuk,J. Kirschner,Gerd Schönhense +22 more
TL;DR: This work presents a novel type of polarimeter that can transport a full image by making use of k-parallel conservation in low-energy electron diffraction and studied specular reflection from Ir (001) because this spin-filter crystal provides a high analyzing power combined with a "lifetime" in UHV of a full day.
Test of band structure calculations for Heusler compounds by spin-resolved photoemission spectroscopy
M. Kolbe,Stanislav Chadov,E. Arbelo Jorge,Gerd Schönhense,Claudia Felser,Hans-Joachim Elmers,Mathias Kläui,Martin Jourdan +7 more
TL;DR: In this article, the electronic density of epitaxial thin films of the Heusler compound Co${}_{2}$MnGa is probed in situ by spin-resolved ultraviolet photoemission spectroscopy.
