Detecting Magnetic Ink Barcodes with Handheld Magnetoresistive Sensors
Sofia Abrunhosa, Ian Gibb, Rita Macedo +4
Information encoding in barcodes using magnetic-based technology is a unique strategy to read data buried underneath non-transparent surfaces since a direct line-of-sight between t…
A four-state magnetic tunnel junction switchable with spin-orbit torques
Shubhankar Das, Ariel Zaig, Moty Schultz +3
We present a magnetic tunnel junction (MTJ) where its two ferromagnetic layers are in the form of a single ellipse (SE) and two-crossing ellipses (TCE). The MTJ exhibits four disti…
Reading thin film permanent magnet irregular patterns using magnetoresistive sensors
Sofia Abrunhosa, Karla J. Merazzo, Tiago Costa +3
Magnetic encoders currently provide accurate positioning information by reading periodic patterns with equally spaced structures or bits. As this technology evolves to fulfill indu…
Dynamic exchange via spin currents in acoustic and optical modes of ferromagnetic resonance in spin-valve structures
A. A. Timopheev, Yu. G. Pogorelov, S. Cardoso +3
Two ferromagnetic layers magnetically decoupled by a thick normal metal spacer layer can be, nevertheless, dynamically coupled via spin currents emitted by the spin-pump and absorb…
Coupling and induced depinning of magnetic domain walls in adjacent spin valve nanotracks
J. Sampaio, L. O'Brien, D. Petit +6
The magnetostatic interaction between magnetic domain walls (DWs) in adjacent nanotracks has been shown to produce strong inter-DW coupling and mutual pinning. In this paper, we ha…
Magnetic field sensor with voltage-tunable sensing properties
Witold Skowroński, Piotr Wiśniowski, Tomasz Stobiecki +3
We report on a magnetic field sensor based on CoFeB/MgO/CoFeB magnetic tunnel junctions. By taking advantage of the perpendicular magnetic anisotropy of the CoFeB/MgO interface, th…
