TL;DR: In this article, the effect of pulsed currents on magnetization reversal was studied on single ferromagnetic nanowires of diameter about 80 nm and 6000 nm length, and the injected current triggered the magnetisation reversal at a value of the applied field distant from the switching field by as much as 20%.

TL;DR: In this article, the direct effect of spin-polarized current on magnetization states is studied on various electrodeposited single contacted nanowires (diameter about 60 nm).

TL;DR: In this paper, the authors measured magnetization reversal triggered by spin injection in electrodeposited Co/Cu/Co pillars (diameter about 60 nm) and showed that irreversible transitions occur only from antiparallel to parallel magnetic configurations and for electrons flow from the polarizer to the analyzer.

TL;DR: In this paper, a photoneutralized neutral beam (NB) system for the future fusion reactor (DEMO Tokamak) has been proposed, where a high power photon flux generated within a Fabry-Perot cavity will overlap, cross and partially photodetach the intense negative ion beam accelerated at high energy (1 or 2 MeV).

TL;DR: In this paper, the full magnetoresistive hysteresis loop is studied as a function of the angle between the applied field and the wire direction, which corresponds to the irreversible switching of the magnetization.
