Racetrack memory based on the controlled motion of magnetic domain walls is a promising new technology for next generation memories, because it combines the speed of DRAMs and the non-volatile properties of flash memories.
Reduction of crystallite size resulted in the increase of magnetization and improved the magnetic properties because the crystallite size approaches that of a magnetic domain, offering thus the possibility to eliminate the influence of the domain walls [11,12].
After an overview, they cover giant, tunnel, and ballistic magnetoresistance (GMR, TMR, BMR) and related phenomena; spin injection and voltage effects in magnetic nanopillars and its applications; dynamics of magnetic domain walks in nanomagnetic systems; theoretical aspects of current-driven magnetization dynamics; micromagnetics of domain wall dynamics in soft nanostrips; and III-V-based ferromagnetic semiconductors.

The paper is titled 'Dynamics of magnetic domain walls under their own inertia' and is authored by Luc Thomas, Rai Moriya, Charles Rettner and Stuart Parkin of IBM Research - Almaden.
The coercivity of crystalline alloys depends strongly of their size because the magnetic domain walls interact with the grain boundaries.
