Journal ArticleDOI
Optical and magneto-optical study of nickel and cobalt ferrite epitaxial thin films and submicron structures
Cameliu Himcinschi,Ionela Vrejoiu,Georgeta Salvan,Michael Fronk,Andreas Talkenberger,Dietrich R. T. Zahn,David Rafaja,Jens Kortus +7 more
TL;DR: In this paper, a larger number of phonon bands were observed in the polarization dependent Raman spectra of the ferrite films than expected for the cubic spinel structures, which is explained by short range ordering of the Ni2+ and Fe3+ cations at the octahedral sites inducing a lowering of the symmetry.
Journal ArticleDOI
Migration-induced field-stabilized polar phase in strontium titanate single crystals at room temperature
Juliane Hanzig,Matthias Zschornak,Matthias Zschornak,Florian Hanzig,Erik Mehner,Hartmut Stöcker,Barbara Abendroth,Christian Röder,Andreas Talkenberger,Gerhard Schreiber,David Rafaja,Sibylle Gemming,Dirk C. Meyer +12 more
TL;DR: In this paper, the authors present in situ x-ray diffraction measurements during and immediately after electroformation of strontium titanate unit cells and show an elongation of the cubic unit cell.
Journal ArticleDOI
Optical properties of epitaxial BiFeO3 thin films grown on LaAlO3
Cameliu Himcinschi,Akash Bhatnagar,Akash Bhatnagar,Andreas Talkenberger,M. Barchuk,Dietrich R. T. Zahn,David Rafaja,Jens Kortus,Marin Alexe +8 more
TL;DR: In this paper, the symmetry of the tetragonal-like BiFeO3 films is discussed based on polarisation dependent Raman measurements and on the comparison with Raman spectra measured for rhombohedral films deposited on TbScO3.
Journal ArticleDOI
Raman spectra and dielectric function of BiCrO3: Experimental and first-principles studies
Cameliu Himcinschi,Ionela Vrejoiu,Torsten Weißbach,Kannan Vijayanandhini,Andreas Talkenberger,Christian Röder,Silvia Bahmann,Dietrich R. T. Zahn,Alexei A. Belik,David Rafaja,Jens Kortus +10 more
TL;DR: In this article, the complex dielectric function of BiCrO3 thin films in the energy range of 073 −98 eV was determined using spectroscopic ellipsometry.
Journal ArticleDOI
Raman spectroscopic investigations of epitaxial BiFeO3 thin films on rare earth scandate substrates
Andreas Talkenberger,Ionela Vrejoiu,Florian Johann,Christian Röder,Gert Irmer,David Rafaja,Gerhard Schreiber,Jens Kortus,Cameliu Himcinschi +8 more
TL;DR: In this article, Raman spectroscopy was used to investigate BiFeO3 epitaxial thin films fabricated by pulsed laser deposition on different scandate substrates.
