Mit Hilfe der Spintronik wird durch Ausnutzung von GMR-Effekten (Giganto Magnetic Resistance) Informationen auf Basis der Rotationsrichtung von Elektronen festgehalten. The word "spintronics" (short for "spin electronics") refers to devices that take advantage of electrons' quantum property called "spin". Electrons don't actually spin around an axis, although in many ways they may behave as if they do. More familiar is the electron's quantum property of "negative charge": Moving charge creates electrical current. Electron spin is a quantum property that has two possible states, either "up" or "down." Aligning spins in a material creates magnetism. Moreover, magnetic fields affect the passage of "up" and "down" electrons differently. Understanding and controlling this property is central to creating a whole new breed of electronic properties. IBM and Stanford University are joining forces on the advanced research and creation of new high-performance, low-power electronics in the emerging field of nanotechnology called "spintronics." To formalize the effort, scientists at IBM's Almaden Research Center and Stanford University created the formation of the IBM-Stanford Spintronic Science and Applications Center (SpinAps, for short). This composite image shows conceptual images of IBM's new "spin flip spectroscopy" in action (left, upper and lower), ideal theoretical plots (middle) showing how the tunneling current changes as the spin is flipped at a particular energy (lower middle) and how that energy changes with magnetic field (upper middle), and actual experimental data (far right) showing the tunneling current change with magnetic field.
