Non-collinear magnetoelectronics

From Digital to Analogue Magnetoelectronics: Theory of Transport in Non-Collinear Magnetic Nanostructures

Magnetoelectronics is mainly digital, i.e. governed by up and down magnetizations. In contrast, analogue magnetoelectronics makes use of phenomena occuring for non-collinear magnetization configurations. Here we review theories which have recently been applied to the transport in noncollinear magnetic nanostructures in two and multiterminal structures, viz. random matrix and circuit theory. Bot...

Imperceptible magnetoelectronics

Future electronic skin aims to mimic nature's original both in functionality and appearance. Although some of the multifaceted properties of human skin may remain exclusive to the biological system, electronics opens a unique path that leads beyond imitation and could equip us with unfamiliar senses. Here we demonstrate giant magnetoresistive sensor foils with high sensitivity, unmatched flexib...

Facilitation from collinear flanks is cancelled by non-collinear flanks

Detection of a central Gabor pattern is facilitated by the presence of collinear flanking patterns. We find that this facilitation is greatly reduced when the collinear flanks are combined with non-collinear flanks to form a coherent surround. These results are unlikely to be explained by mechanisms that merely transduce local contrast in a nonlinear fashion. A model wherein the outputs of such...

Magnetoelectronics with magnetoelectrics

Magnetoelectric fi lms are proposed as key components for spintronic applications. The net magnetic moment created by an electric fi eld in a magnetoelectric thin fi lm infl uences the magnetization state of a neighbouring ferromagnetic layer through exchange coupling. Pure electrical control of magnetic confi gurations of giant magnetoresistance spin valves and tunnelling magnetoresistance ele...
