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…
