Twisted Magnetic Fields Increase Potential Density of Data Storage 20x

The work revolves around twisted magnetic fields known as skyrmions, which can retain their structure even when packed very densely.
In the latest development, Kristen von Bergmann and her team at the University of Hamburg have figured out how to deliberately write and erase skyrmions, which is a first for the scientific community. The method relies on a scanning tunneling microscope, which applies spin polarization to a current of electrons that are stored on a magnetic surface.
The technology is nowhere near ready for consumer use — it’s currently around 60 percent reliable, and requires an ambient temperature that’s on par with liquid helium — but it’s worth keeping an eye on as development progresses.
