Journal ArticleDOI
Nanometer spot allocation for Raman spectroscopy on ferroelectrics by polarization and piezoresponse force microscopy
TL;DR: In this article, the authors report the 100% correlation between polarized light microscopy (PLM), piezoresponse force microscopy, and micro-Raman spectroscopy when investigating domain-rich ferroelectric systems, and show unambiguous differentiation between a and c domains on the submicrometer scale using the B2 mode of lattice vibrations.
Journal ArticleDOI
Piezoelectric Response of Polycrystalline Silicon‐Doped Hafnium Oxide Thin Films Determined by Rapid Temperature Cycles
C. Mart,Thomas Kampfe,R. Hoffmann,Sophia Eßlinger,Sven Kirbach,Kati Kühnel,Malte Czernohorsky,Lukas M. Eng,Wenke Weinreich +8 more
Journal ArticleDOI
Quantitative determination of the charge carrier concentration of ion implanted silicon by IR-near-field spectroscopy
Rainer Jacob,Stephan Winnerl,Harald Schneider,Manfred Helm,Marc Tobias Wenzel,Hans-Georg von Ribbeck,Lukas M. Eng,Susanne C. Kehr +7 more
TL;DR: A combination of a scattering-type near-field infrared microscope with a free-electron laser as an intense, tunable radiation source to spatially and spectrally resolve buried doped layers in silicon yields quantitatively correct values for the concentration of the activated carriers.
Journal ArticleDOI
Macroscopic manifestation of domain-wall magnetism and magnetoelectric effect in a Néel-type skyrmion host

Widmann,Somnath Ghara,Peter Lunkenheimer,Vladimir Tsurkan,Vladimir Tsurkan,Erik Neuber,Dmytro Ivaneyko,Peter Milde,Lukas M. Eng,Andrey O.

TL;DR: In this article, the authors report a magnetic state in GaV4Se8 which emerges exclusively in samples with mesoscale polar domains and not in polar mono-domain crystals, and ascribe this additional transition to the transformation of distinct magnetic textures, confined to polar domain walls (DW), to the ferromagnetic state.
Journal ArticleDOI
Heuristic Description of Magnetoelectricity of Cu2OSeO3
TL;DR: A heuristic description of the magnetoelectric properties in CuO2SeO3 is developed and the model successfully describes the dependency of the electric polarization on the magnetization in all magnetically modulated phases.
