    Kostenvergleich zwischen CO2-Laserschneiden und Stanzen/Nibbeln

    Laser machines make possible the processing of nearly every geometric form of a workpiece. The effects on the processing costs are: minimal set-up costs and no need for special tools. Punching and nibbling mac...

    Switching of Ferroelectric Nanostructures

    Ferroelectric domain structures of epitaxial SrBi2Ta2O9 (SBT), BaBi4Ti4O15 (BBiT) and Bi4Ti3O12 (BiT) thin films as well as PZT nanostructures have been imaged at the nanometer scale. The surface polarization sta...

    Nano-Size Ferroelectric Structures

    In the present work ferroelectric structures with lateral sizes as small as 100 nm were fabricated by electron beam direct writing. Switching of single 100 nm cells was achieved and piezoelectric hysteresis lo...

    Probing strain propagation in nanolayered perovskites by diffraction of femtosecond x-rays

    Propagating strain waves in SrTiO3, launched from PbZr0.2Ti0.8O3 films are measured by time-resolved x-ray diffraction. X-ray interference among contributions from differently strained regions allow to determine ...

    Ferroelectric materials and structures suitable for data storage: The role of microscopies in establishing preparation-microstructure-property relations

    Among the various possible routes towards solid-state non-volatile random access memories (NV-RAMs) of high memory density, ferroelectric random access memories (FRAMs) offer very good prospects. Non-volatilit...

    Femtosecond X-ray Diffraction Study of the Ultrafast Coupling between Magnetization and Structure in the Ferromagnet SrRuO3

    Femtosecond optical excitation of magnetically ordered SrRuO3 nanolayers leads to an ultrafast demagnetization and a concomitant magnetoelastic contractive stress. The resulting ultrafast structural response of t...
