Magnetic, thermal, and topographic imaging with a nanometer-scale SQUID-on-cantilever scanning probe
M. Wyss, K. Bagani, D. Jetter +7
Scanning superconducting quantum interference device (SQUID) microscopy is a magnetic imaging technique combining high-field sensitivity with nanometer-scale spatial resolution. St…
Magnetic anisotropy of individual maghemite mesocrystals
B. Gross, S. Philipp, E. Josten +4
Interest in creating magnetic metamaterials has led to methods for growing superstructures of magnetic nanoparticles. Mesoscopic crystals of maghemite () n…
Nanowire magnetic force sensors fabricated by focused electron beam induced deposition
H. Mattiat, N. Rossi, B. Gross +6
We demonstrate the use of individual magnetic nanowires (NWs), grown by focused electron beam induced deposition (FEBID), as scanning magnetic force sensors. Measurements of their…
Magnetic force sensing using a self-assembled nanowire
N. Rossi, B. Gross, F. Dirnberger +2
We present a scanning magnetic force sensor based on an individual magnet-tipped GaAs nanowire (NW) grown by molecular beam epitaxy. Its magnetic tip consists of a final segment 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 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…
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…
