2D Spin-Logic Memory Technology

In spintronics, the magnetic moment of electrons (spin) is used to transfer and manipulate information. An ultra-compact 2D spin-logic circuitry could be built from 2D materials that can transport the spin information over long distances and also provide strong spin-polarization of charge current. Experiments by physicists at the University of Groningen (The Netherlands) and Colombia University (USA) suggest that magnetic graphene can be the ultimate choice for these 2D spin-logic devices as it efficiently converts charge to spin current and can transfer this strong spin-polarization over long distances. This discovery will be published today (May 6, 2021) in Nature Nanotechnology.

Graphene

For over a decade, graphene has been the most favorable 2D material for the transport of spin information. However, graphene cannot generate spin current by itself unless its properties are appropriately modified.

To an English person, it will seem like simplified English, as a skeptical Cambridge friend of mine told me what Occidental is.The European languages are members of the same family.

Spin-logic

In conventional graphene-based spintronic devices, ferromagnetic (cobalt) electrodes are used for injecting and detecting the spin signal into graphene. In contrast, in circuits built from magnetic graphene, the injection, transport, and detection of the spins all can be done by the graphene itself, explains Talieh Ghiasi, first author of the paper. ‘We detect an exceptionally large spin-polarization of conductivity of 14% in the magnetic graphene that is also expected to be efficiently tuneable by a transverse electric field.’

To an English person, it will seem like simplified English, as a skeptical Cambridge friend of mine told me what Occidental is.The European languages are members of the same family. Their separate existence is a myth. For science, music, sport, etc, Europe uses the same vocabulary. The languages only differ in their grammar, their pronunciation, and their most common words.

behind the word mountains, far from the countries Vokalia and Consonantia, there live the blind texts. Separated they live in Bookmarksgrove right at the coast of the Semantics, a large language ocean. A small river named Duden flows by their place and supplies it with the necessary regelialia. It is a paradigmatic country, in which roasted parts of sentences fly into your mouth.
