Methods for traceable scanning magnetometry using single nitrogen vacancy centers in diamond: determining orientation, distance and localization
Nikhita Khera, Ephraim Spindler, Yanis Abdedou +7
Individual, scannable nitrogen vacancy (NV) centers in single crystal diamond nanostructures enable nanoscale, quantitative imaging of magnetic stray fields. Nevertheless, importan…
Phase-dependent parametric amplification of propagating spin waves in YIG nanostructures enabled by local inhomogeneities
Akira Lentfert, Ephraim Spindler, Björn Heinz +2
As magnonics evolves towards non-conventional computing, the development of phase-conserving and phase-sensitive amplification mechanisms becomes increasingly important. A particul…
Nonlinear frequency shift and bistability of magnon-polarons
Kevin Künstle, Matthias Wagner, Philipp Knaus +7
We investigate the nonlinear dynamics of strongly coupled surface acoustic waves (SAWs) and spin waves (SWs) in a magnetoacoustic resonator based on a YIG/ZnO heterostructure by co…
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…
