Journal ArticleDOI
Epitaxial growth and transport properties of Sr2CrWO6 thin films
J. B. Philipp,D. Reisinger,M. Schonecke,Matthias Opel,Achim Marx,Andreas Erb,Lambert Alff,Rudolf Gross +7 more
TL;DR: In this article, the authors report on the preparation and characterization of epitaxial thin films of the double perovskite Sr2CrWO6 by pulsed laser deposition.
Journal ArticleDOI
Spin Hall magnetoresistance in antiferromagnetic insulators
Stephan Geprägs,Matthias Opel,Johanna Fischer,Olena Gomonay,Philipp Schwenke,Matthias Althammer,Hans Huebl,Rudolf Gross +7 more
TL;DR: In this article, the spin Hall magnetoresistance (SMR) was used to probe the antiferromagnetic spin structure via simple electrical transport experiments by investigating the easy-plane insulators α − Fe 2 O 3 (hematite) and NiO in bilayer heterostructures with a Pt heavy-metal top electrode.
Journal ArticleDOI
Zinc oxide –From dilute magnetic doping to spin transport
Matthias Opel,Sebastian T. B. Goennenwein,Matthias Althammer,Karl-Wilhelm Nielsen,Eva-Maria Karrer-Müller,Sebastian Bauer,Konrad Senn,Christoph Schwark,Christian Weier,Gernot Güntherodt,Bernd Beschoten,Rudolf Gross +11 more
TL;DR: In this paper, a comprehensive investigation of ZnO:Co thin films based on the combined measurement of macroscopic and microscopic properties was conducted, and no evidence for carrier-mediated itinerant ferromagnetism was found.
Journal ArticleDOI
Phonon anomalies in FeS
Andreas Baum,Ana Milosavljević,Nenad Lazarević,M. M. Radonjić,B. Nikolić,M. Mitschek,Z. Inanloo Maranloo,Maja Šćepanović,M. Grujić-Brojčin,Nenad Stojilovic,Nenad Stojilovic,Matthias Opel,Aifeng Wang,Cedomir Petrovic,Zoran B. Popović,Zoran B. Popović,R. Hackl +16 more
TL;DR: In this paper, the authors present results from light scattering experiments on tetragonal FeS with the focus placed on lattice dynamics, identifying the Raman active phonon modes, a second order scattering process involving two acoustic phonons, and contributions from potentially defect-induced scattering.
Journal ArticleDOI
Ferromagnetism in epitaxial Zn0.95Co0.05O films grown on ZnO and Al2O3
Karl-Wilhelm Nielsen,Sebastian Bauer,M. Lübbe,S. T. B. Goennenwein,Matthias Opel,J. Simon,Werner Mader,Rudolf Gross +7 more
TL;DR: In this article, the possible mechanisms resulting in strong ferromagnetic coupling in transition metal (TM)-doped ZnO and other diluted magnetic semiconductors (DMS) are reviewed and the prerequisites for the observation of room temperature ferromagnetism in DMS are defined.
