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…
