Magnetic and structural properties of epitaxial Er-substituted yttrium iron garnet films grown by pulsed laser deposition
Lukas Flajsman, Lars Peeters, Armi Kosunen +3
Er-substituted yttrium iron garnet (Er:YIG) holds the potential of combining the low magnetic damping of YIG with the telecom-band optical transitions of ions, mak…
Direct time domain sampling of sub-THz coherent acoustic phonon spectra in SrTiO using ultrafast X-ray diffraction
Roman Shayduk, Marc Herzog, André Bojahr +8
We synthesize sub-THz longitudinal quasi-monochromatic acoustic phonons in a SrTiO single crystal using a SrRuO/SrTiO superlattice as an optical-acoustic transducer. Th…
Stability of 71° stripe domains in epitaxial BiFeO3 films upon repeated electrical switching
Florian Johann, Alessio Morelli, Ionela Vrejoiu
The 71° stripe domain patterns of epitaxial BiFeO3 thin films are frequently being explored to achieve new functional properties, dissimilar from the BiFeO3 bulk properties. We sho…
Cross talk by extensive domain wall motion in arrays of ferroelectric nanocapacitors
Yunseok Kim, Hee Han, Ionela Vrejoiu +3
We report on extensive domain wall motion in ferroelectric nanocapacitor arrays investigated by piezoresponse force microscopy. Under a much longer or higher bias voltage pulse, co…
Impact of misfit strain on the properties of tetragonal Pb(Zr,Ti)O3 thin film heterostructures
Ludwig Geske, I. B. Misirlioglu, Ionela Vrejoiu +2
Heterostructures consisting of PbZr0.2Ti0.8O3 and PbZr0.4Ti0.6O3 films grown on a SrTiO3 (100) substrate with a SrRuO3 bottom electrode were prepared by pulsed laser deposition. Us…
Vortex Ferroelectric Domains
A. Gruverman, D. Wu, H. -J. Fan +4
We show experimental switching data on microscale capacitors of lead-zirconate-titanate (PZT), which reveal time-resolved domain behavior during switching on a 100-ns scale. For sm…
