Current-driven dynamics and ratchet effect of skyrmion bubbles in a ferrimagnetic insulator
Saül Vélez, Sandra Ruiz-Gómez, Jakob Schaab +8
Magnetic skyrmions are compact chiral spin textures that exhibit a rich variety of topological phenomena and hold potential for developing high-density memory devices and novel com…
Charged ferroelectric domain walls for deterministic a.c. signal control
J. Schultheiß, E. Lysne, L. Puntigam +5
The direct current (d.c.) conductivity and emergent functionalities at ferroelectric domain walls are closely linked to the local polarization charges. Depending on the charge stat…
Intrinsic and extrinsic conduction contributions at nominally neutral domain walls in hexagonal manganites
J. Schultheiß, J. Schaab, D. R. Småbråten +5
Conductive and electrostatic atomic force microscopy (cAFM and EFM) are used to investigate the electric conduction at nominally neutral domain walls in hexagonal manganites. The E…
Electrostatic potential mapping at ferroelectric domain walls by low-temperature photoemission electron microscopy
J. Schaab, K. Shapovalov, P. Schoenherr +10
Low-temperature X-ray photoemission electron microscopy (X-PEEM) is used to measure the electric potential at domain walls in improper ferroelectric Er0.99Ca0.01MnO3. By combining…
Magnetic properties and domain structure of ultrathin yttrium iron garnet/Pt bilayers
Johannes Mendil, Morgan Trassin, Qingqing Bu +10
We report on the structure, magnetization, magnetic anisotropy, and domain morphology of ultrathin yttrium iron garnet (YIG)/Pt films with thickness ranging from 3 to 90 nm. We fin…
High-speed domain wall racetracks in a magnetic insulator
Saül Vélez, Jakob Schaab, Martin S. Wörnle +9
Recent reports of current-induced switching of ferrimagnetic oxides coupled to a heavy metal layer have opened realistic prospects for implementing magnetic insulators into electri…
