Electrical Characterization of DNA Origami Structures with PEG-PLL coating for improved robustness
Florian Heimbach, Johann Bohlen, Hans Rabus +2
Electrical conductivity of DNA has been a controversial topic since it was first proposed in 1962. Disparities in the experimental results can often be explained by differences of…
Observation of vortex-nucleated magnetization reversal in individual ferromagnetic nanotubes
A. Mehlin, B. Gross, M. Wyss +6
The reversal of a uniform axial magnetization in a ferromagnetic nanotube (FNT) has been predicted to nucleate and propagate through vortex domains forming at the ends. In dynamic…
Imaging stray magnetic field of individual ferromagnetic nanotubes
D. Vasyukov, L. Ceccarelli, M. Wyss +11
We use a scanning nanometer-scale superconducting quantum interference device to map the stray magnetic field produced by individual ferromagnetic nanotubes (FNTs) as a function of…
Angular Dependent Magnetization Dynamics of Kagome Artificial Spin Ice Incorporating Topological Defects
V. S. Bhat, F. Heimbach, I. Stasinopoulos +1
We report angular-dependent spin-wave spectroscopy on kagome artificial spin ice made of large arrays of interconnected Ni80Fe20 nanobars. Spectra taken in saturated and disordered…
Imaging magnetic vortex configurations in ferromagnetic nanotubes
M. Wyss, A. Mehlin, B. Gross +9
We image the remnant magnetization configurations of CoFeB and permalloy nanotubes (NTs) using x-ray magnetic circular dichroism photo-emission electron microscopy. The images prov…
THz-circuits driven by photo-thermoelectric graphene-junctions
Andreas Brenneis, Felix Schade, Simon Drieschner +4
For future on-chip communication schemes, it is essential to integrate nanoscale materials with an ultrafast optoelectronic functionality into high-frequency circuits. The atomical…
Magnetization Dynamics of Topological Defects and the Spin Solid in Kagome Artificial Spin Ice
V. S. Bhat, F. Heimbach, I. Stasinopoulos +1
We report broadband spin-wave spectroscopy on kagome artificial spin ice (ASI) made of large arrays of interconnected NiFe nanobars. Spectra taken in saturated and di…
Dynamic cantilever magnetometry of individual CoFeB nanotubes
B. Gross, D. P. Weber, D. Rüffer +5
We investigate single CoFeB nanotubes with hexagonal cross-section using dynamic cantilever magnetometry (DCM). We develop both an analytical model based on the Stoner-Wohlfarth ap…
Magnetization reversal of an individual exchange biased permalloy nanotube
A. Buchter, R. Wölbing, M. Wyss +14
We investigate the magnetization reversal mechanism in an individual permalloy (Py) nanotube (NT) using a hybrid magnetometer consisting of a nanometer-scale SQUID (nanoSQUID) and…
