Reversible magneto ionics in crystallized W Co20Fe60B20 MgO HfO2 ultra-thin films with perpendicular magnetic anisotropy
Song Chen, Elmer Monteblanco, Benjamin Borie +2
We have investigated electric field (E-field) induced modulation of perpendicular magnetic anisotropy (PMA) in both amorphous and crystalline W/CoFeB/MgO/HfO2 ultra-thin films. We…
Control of magnetoelastic coupling in Ni/Fe multilayers using He ion irradiation
Giovanni Masciocchi, Johannes Wilhelmus van der Jagt, Maria-Andromachi Syskaki +10
This study reports the effects of post-growth He irradiation on the magneto-elastic properties of a / multi-layered stack. The progressive intermixing caused by He…
Geometrically enhanced closed-loop multi-turn sensor devices that enable reliable magnetic domain wall motion
Benjamin Borie, Jürgen Wahrhusen, Hubert Grimm +1
We experimentally realize a sophisticated structure geometry for reliable magnetic domain wall-based multi-turn-counting sensor devices, which we term closed-loop devices that can…
Optimization of Permalloy properties for magnetic field sensors using He irradiation
Giovanni Masciocchi, Johannes Wilhelmus van der Jagt, Maria-Andromachi Syskaki +7
Permalloy, despite being a widely utilized soft magnetic material, still calls for optimization in terms of magnetic softness and magnetostriction for its use in magnetoresistive s…
Angular dependence of the domain wall depinning field in the sensors with segmented corners
Daniel Heinze, Benjamin Borie, Jürgen Wahrhusen +2
Rotating domain wall based sensors that have recently been developed are based on a segmented looping geometry. In order to determine the crucial pinning of domain walls in this sp…
