Journal ArticleDOI
Size effect in Mn 2 + -doped BaTiO 3 nanopowders observed by electron paramagnetic resonance
TL;DR: In this paper, the authors used x-ray diffraction (XRD) and electron paramagnetic resonance (EPR) techniques, taking EPR spectra in the X (9.5 GHz), Q (34.2 GHz), and W (94.1 GHz) frequency bands.
Journal ArticleDOI
Study of the tetragonal-to-cubic phase transition in PbTiO3 nanopowders
Emre Erdem,H.-C. Semmelhack,Rolf Böttcher,Holger Rumpf,Juras Banys,Anke Matthes,Hans-Jürgen Gläsel,Dietmar Hirsch,Eberhard Hartmann +8 more
TL;DR: In this article, the CPP (combined polymerization and pyrolysis) preparation route, in its enhanced liquid-precursor-based version, was combined with consecutive soft milling for studies of temperature and size-dependent structural changes occurring in ferroelectric lead titanate.
Journal ArticleDOI
Crystal structure and related properties of copper-doped barium titanate ceramics
TL;DR: In this article, the influence of copper on the crystallographic phase and the microstructure of ceramics with a nominal composition of BaTiO3+0.02, BaO+x-CuO (0⩽x 0.02) was investigated.
Journal ArticleDOI
Electron paramagnetic resonance of Zn 1 − x Mn x O thin films and single crystals
M. Diaconu,Heidemarie Schmidt,Andreas Pöppl,Rolf Böttcher,J. Hoentsch,Alexander Klunker,Daniel Spemann,Holger Hochmuth,Michael Lorenz,Marius Grundmann +9 more
TL;DR: In this article, the fine and hyperfine structure splitting parameters were determined by modeling the experimental spectra and extrapolating the lattice-distortion-dependent fine-structure parameters determined for samples with a Mn content of 0.035.
Journal ArticleDOI
Structural and optical properties of chromium-doped hexagonal barium titanate ceramics
TL;DR: In this paper, the influence of chromium on the crystallographic phase and the microstructure of ceramics with the nominal composition BaTiO3+0.04BaO+xCr2O3 (0≤x≤0.025) was investigated by systematic studies of x-ray diffraction (XRD) and electron paramagnetic resonance (EPR).
