Journal ArticleDOI

Enhanced ferrimagnetism in auxetic NiFe 2 O 4 in the crossover to the ultrathin-film limit

Michael Hoppe, +5 more
- 24 Feb 2015 - 
TL;DR: In this paper, the effect of reduced dimensionality in the crossover from bulk-like to ultrathin films was investigated, and it was shown that the inverse spinel lattice of the ferrimagnetic oxide (NiFe) has a cationic coordination independent of the film thickness.
Journal ArticleDOI

Chemical stability of the magnetic oxide EuO directly on silicon observed by hard x-ray photoemission spectroscopy

Christian Caspers, +11 more
- 18 Nov 2011 - 
TL;DR: In this paper, a detailed study of the electronic structure and chemical state of high-quality stoichiometric EuO and O-rich thin films grown directly on silicon without any buffer layer using hard x-ray photoemission spectroscopy was presented.
Journal ArticleDOI

Electronic structure of EuO spin filter tunnel contacts directly on silicon

Christian Caspers, +11 more
- 01 Dec 2011 - 
TL;DR: In this paper, the authors present an electronic structure study of a magnetic oxide/ semiconductor model system, EuO on silicon, which is dedicated for efficient spin injection and spin detection in silicon-based spintronics devices.
Journal ArticleDOI

Ultrathin magnetic oxide EuO films on Si(001) using SiOx passivation—Controlled by hard x-ray photoemission spectroscopy

Christian Caspers, +6 more
- 13 Mar 2013 - 
TL;DR: In this article, a chemical and structural optimization of ultrathin magnetic oxide EuO films on silicon is presented. But the results are limited to a 4'nm-thin film and cannot be used for spin functional tunnel contacts in spin FETs.
