Journal ArticleDOI
Magnetic Domain-Wall Logic
TL;DR: “Spintronics,” in which both the spin and charge of electrons are used for logic and memory operations, promises an alternate route to traditional semiconductor electronics.
Journal ArticleDOI
Submicrometer ferromagnetic NOT gate and shift register.
Dan A. Allwood,Gang Xiong,M.D. Cooke,C. C. Faulkner,Del Atkinson,N. Vernier,Russell P. Cowburn +6 more
TL;DR: An all-metallic submicrometer device is demonstrated experimentally at room temperature that performs logical NOT operations on magnetic logic signals.
Journal ArticleDOI
Magnetic domain-wall dynamics in a submicrometre ferromagnetic structure.
TL;DR: Room-temperature measurements of the propagation velocity of a domain wall in a single-layer planar Ni80Fe20 ferromagnetic nanowire 200 nm wide indicate that lateral confinement does not significantly affect the gyromagnetic spin damping parameter to the extreme extent previously suggested.
Journal ArticleDOI
Domain wall propagation in magnetic nanowires by spin-polarized current injection
TL;DR: In this paper, the authors demonstrate the movement of a head-to-head domain wall through a magnetic nanowire of permalloy (Ni81Fe19) by passing an electrical current through the domain wall and without any external magnetic field applied.
Journal ArticleDOI
Forgery: 'fingerprinting' documents and packaging.

TL;DR: In this article, unique surface imperfections serve as an easily identifiable feature in the fight against fraud and can be used as a warning sign of the existence of a malicious con artist.
