Latest Domain wall Stories
While searching for ever smaller devices that can be used as data storage systems and novel sensors, physicists at Johannes Gutenberg University Mainz (JGU) have directly observed magnetization dynamics processes in magnetic nanowires and thus paved the way for further research in the field of nanomagnetism.
For the first time scientists at Helmholtz-Zentrum Berlin have managed to create 3-dimensional images of these domains deep within magnetic materials.
Just as the path of photons of light can be directed by a mirror, atoms possessing a magnetic moment can be controlled using a magnetic mirror.
After running a series of complex computer simulations, researchers have found that flaws in the structure of magnetic nanoscale wires play an important role in determining the operating speed of novel devices using such nanowires to store and process information.
The logic and memory functions of future electronic devices could shrink dramatically â€“ to one or two nanometers (billionths of a meter) instead of the many tens of nanometers that characterize todayâ€™s most advanced elements - if a way can be found to control domain walls, the ultrathin transition zones that separate regions of a material having different magnetic, electric, or other properties.
