Direct Laser Writing of Ferromagnetic Nickel Utilizing the Principle of Sensitized Triplet-Triplet Annihilation Upconversion
Kristin E. J. Kühl, Katharina Rediger, Nikhita Khera +5
Direct laser writing of ferromagnetic microstructures is of great interest for sensing and data storage in compact three-dimensional architectures. However, reliable direct laser w…
Nanoscale Dipolar Fields in Artificial Spin Ice Probed by Scanning NV Magnetometry
Ephraim Spindler, Vinayak Shantaram Bhat, Elke Neu +2
We investigate dipolar coupling fields in two square-lattice artificial spin ice (ASI) systems with different lattice constants using scanning probe microscopy based on a single ni…
Charge accumulation by Direct Magnetoelectric Effect in ScAlN/Ni Nanoscale Devices
Federica Luciano, Emma Van Meirvenne, Ephraim Spindler +6
This work investigates the direct magnetoelectric effect in thin-film lab scale composite heterostructures comprising a 100 nm thick piezoelectric Sc0.4Al0.6N (ScAlN) and a magneto…
Ratchet motion of magnetic skyrmions driven by surface acoustic sawtooth waves
Philipp Schwenke, Ephraim Spindler, Vitaliy I. Vasyuchka +3
The manipulation of skyrmions by surface acoustic waves (SAW) has garnered significant interest in the field of spintronic devices. Previous studies established that skyrmions can…
