We report the observation and micromagnetic analysis of current-driven magnetization
switching in nanoscale ring-shaped magnetic tunnel junctions. When the electric current …

Nanostructured magnetic tunnel junction rings (MTJ) based on CoFeB free layer were
fabricated to investigate the corresponding magnetization reversal processes. The …

We have measured domain wall magnetoresistance in a single lithographically constrained
domain wall. An H-shaped Ni nanobridge was fabricated by e-beam lithography with the two …

The giant magnetoresistance of Ni Fe∕ Cu∕ Co∕ Ir Mn spin valve elliptical rings with 3.2∕
1.9 μ m major/minor diameter and widths of 340–370 nm has been characterized in a …

We studied thermal fluctuations in magnetoresistance (MR) signals originating from
geometrically confined magnetic walls (GCMWs) of nanometer size. To this end, we …

We report an effect of field cooling direction on the magnetoresistance of ring-shaped
magnetic tunnel junctions consisting of Ta 5/Cu 20/Ta 5/NiFe 2/Cu 5/MnIr 10/CoFe 4/Al–N …

In magnetic materials, domains of magnetic orientation in opposite direction are often
alternated. The transition in orientation between these domains, the domain wall, is not …

We report a reproducible top down fabrication procedure for a single domain wall
magnetoresistance H-shaped device. A bi-layer e-beam lift-off process is used and the e …

Magnetic thin film ring structures show distinct magnetic states and highly reproducible
switching behavior, which makes them candidates for multiple magnetoelectronic and …
