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…
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…
Quantum sensing magnonic number states using a bosonic mode as the probe
Bashab Dey, Sonu Verma, Mathias Weiler +1
Sensing number states of a magnonic mode has been accomplished using a superconducting qubit by realizing an effective dispersive interaction between the two systems. Here, we theo…
Spontaneous Emergence of Phase Coherence in a quasiparticle Bose-Einstein Condensate
Malte Koster, Matthias R. Schweizer, Timo Noack +6
Since their prediction by Einstein at the dawn of quantum mechanics, Bose-Einstein condensates (BECs), owing to their property to show quantum phenomena on macroscopic scales, are…
Misfit layer superconductors, tuneable bulk heterostructures with strong 2D effects
Tomas Samuely, Martin Gmitra, Tristan Cren +2
Atomically thin layered materials are systems with zero limit bulk-to-surface ratio. Their physical properties are determined by two-dimensionality and strongly affected by interfa…
