The future of spintronics

Developing new hybrid organic-inorganic (Hoi) materials featuring strong and tuneable spin-transfer efficiency at the interfaces. This is the goal of 'Next Generation Hybrid Interfaces for Spintronic Applications' (Hints) project, funded with 3,874,360.00 Euro granted by the European Commission in the 7th Framework Programme and coordinated by Valentin Dediu, researcher at Cnr-Institute of nanostructered materials (Cnr-Ismn). It is carried out by a consortium of 14 leading research institutions coming from eight countries, each of them with specific roles and different levels of involvement. The consortium is composed by seven universities, three research centers and four companies spread across Europe.

One of the main characteristics of all organic based Ict devices is the intrinsic hybrid combination of organic active materials with inorganic electrodes. Their greatest advantage is the possibility of low-cost processing and the enormous choice of molecules, most of which are still unexplored. The ambitious approach of Hints is implemented by designing new materials with improved spin transfer efficiency and transport. Hints will constantly benchmark the material parameters and properties with device demands.

The Eu project has now achieved its first year of life and the first results have been recently presented in Valencia. "This first year of life was characterized by a set of encouraging results among which we can mention the achievement of strong Giant magnetoresistance modulation (Gmr) via both proxity effect and electrical gating at spin injecting and collecting hybrid interfaces; promissing preliminary results of self-assembled monolayers assisted Tunnel magnetoresistance (Tmr) junctions; extraordinary first observation of the Gmr inversion in a Gmr device via electrical field gating and first modification/adjustment of the technological tools (effusion cells) as required by the needs driven by Hints objectives", says Alek Dediu.
