ChiralMEM: a Novel Concept for High Density Magnetic Memory Technology

Atkinson D., Eastwood D.S., Bath M., Durham University, UK

ChiralMEM is a new approach to higher density magnetic random access memory for information technology [1-3]. It is based on memory cells capable of storing multiple bits of information per cell in contrast to the [...]

First-principles Modeling of Magnetic Memory Components — Preliminary Results on the Effects of Interface Oxides

Stilling M., Stokbro K., Flensberg K., Atomistix, DK

Magnetotunnel junctions (MTJs), exhibiting high tunneling magnetoresistance (TMR), are currently being employed in new generations of hard disk drive (HDD) read heads and novel magnetic random access memory (MRAM) technology. We have modeled such spintronic [...]

A Sub-40nm Nanostructured La0.7Sr0.3MnO3 Planar Magnetic Memory

Arnal T., Bibes M., Lecoeur Ph., Mercey B., Prellier W., Haghiri-Gosnet A.M., Institut d'Electronique Fondamentale IEF/UMR8622, FR

A single-step nanolithography planar process, which allows generating the core-element of a spin-polarized magnetic memory in the fully spin-polarized La0.7Sr0.3MnO3 (LSMO) manganite, is reported. Taking benefit of the proximity effects due to backscattered electrons, a [...]
