Capture of nanomagnetic 'fingerprints' a boost for next-generation information storage media
Date:1/29/2009

In the race to develop the next generation of storage and recording media, a major hurdle has been the difficulty of studying the tiny magnetic structures that will serve as their building blocks. Now a team of physicists at the University of California, Davis, has developed a technique to capture the magnetic "fingerprints" of certain nanostructures even when they are buried within the boards and junctions of an electronic device. This breakthrough in nanomagnetism was published in the Jan. 19 issue of Applied Physics Letters.

The past decade has witnessed a thousand-fold increase in magnetic recording area density, which has revolutionized the way information is stored and retrieved. These advances are based on the development of nanomagnet arrays which take advantage of the new field of spintronics: using electron spin as well as charge for information storage, transmission and manipulation.

But due to the miniscule physical dimensions of nanomagnets some are as small as 50 atoms wide observing their magnetic configurations has been a challenge, especially when they are not exposed but built into a functioning device.

"You can't take full advantage of these nanomagnets unless you can 'see' and understand their magnetic structures not just how the atoms and molecules are put together, but how their electronic and magnetic properties vary accordingly," said Kai Liu, a professor and Chancellor's Fellow in physics at UC Davis. "This is difficult when the tiny nanomagnets are embedded and when there are billions of them in a device."

To tackle this challenge, Liu and three of his students, Jared Wong, Peter Greene and Randy Dumas, created copper nanowires embedded with magnetic cobalt nanodisks. Then they applied a series of magnetic fields to the wires and measured the responses from the nanodisks. By starting each cycle at full saturation that is, using a field strong enough to align all the nanomagnets then
