IBM Scientists Create World's Smallest Magnetic Memory Bit, Paving The Way For 100 times denser HDDs and SSDs


Scientists from IBM Research have successfully demonstrated the ability to store information in as few as 12 magnetic atoms, a breakthough that could lead multiply the capacity of today's storage media.

For comparison, today's disk drives use about one million atoms to store a single bit of information.

While silicon transistor technology has become cheaper, denser and more efficient, fundamental physical limitations suggest this path of conventional scaling is unsustainable. Alternative approaches are needed to continue the rapid pace of computing innovation.

By taking a novel approach and beginning at the smallest unit of data storage, the atom, scientists demonstrated magnetic storage that is at least 100 times denser than today's hard disk drives and solid state memory chips. Future applications of nanostructures built one atom at a time, and that apply an unconventional form of magnetism called antiferromagnetism, could allow people and businesses to store 100 times more information in the same space.

"The chip industry will continue its pursuit of incremental scaling in semiconductor technology but, as components continue to shrink, the march continues to the inevitable end point: the atom. Were taking the opposite approach and starting with the smallest unit -- single atoms -- to build computing devices one atom at a time." said Andreas Heinrich, the lead investigator into atomic storage at IBM Research ? Almaden, in California.

How it Works

The most basic piece of information that a computer understands is a bit. Much like a light that can be switched on or off, a bit can have only one of two values: "1" or "0". Until now, it was unknown how many atoms it would take to build a reliable magnetic memory bit.

With properties similar to those of magnets on a refrigerator, ferromagnets use a magnetic interaction between its constituent atoms that align all their spins - the origin of the atoms' magnetism - in a single direction. Ferromagnets have worked well for magnetic data storage but a major obstacle for miniaturizing this down to atomic dimensions is the interaction of neighboring bits with each other. The magnetization of one magnetic bit can strongly affect that of its neighbor as a result of its magnetic field. Harnessing magnetic bits at the atomic scale to hold information or perform useful computing operations requires precise control of the interactions between the bits.

The scientists at IBM Research used a scanning tunneling microscope (STM) to atomically engineer a grouping of twelve antiferromagnetically coupled atoms that stored a bit of data for hours at low temperatures. Taking advantage of their inherent alternating magnetic spin directions, they demonstrated the ability to pack adjacent magnetic bits much closer together than was previously possible. This greatly increased the magnetic storage density without disrupting the state of neighboring bits.
