Spintronics: A growing science

Nature Materials 6 (2007) 798-799

The integration of spintronic elements with silicon technologies in order to produce active spintronic devices with both power gain and spin function that can store and process data. Schmehl and his colleagues have succeeded in making high quality materials with europium oxide, which shows excellent epitaxy on their silicon substrate and their conductivity may be readily and sensitively varied to suit the application. Spintronics uses thin slices of ferromagnetic materials as spin sources and detectors. The epitaxial growth on silicon shows that the interface chemistry problems have been eliminated and goes well for integration with conventional electronics. One most possible field for spintronics is to transferred-electron phenomena to generate a spin-Gunn effects by which spin-dependent negative resistance might be realizable.
