Spintronics Volume 50, Number 1, 2006 Click to enlarge
RD 50-1
Spintronics (spin-based electronics) pertains to microelectronic devices that rely on electron spin rather than charge for memory and logic applications. This issue focuses on MRAM (magnetic random access memory), offering the potential for nonvolatile, on-chip storage—and on spin-based phenomena in semiconductors, offering the potential for devices that would function at exceptionally low power.
