Shrinking Magnetic Storage Media Down to the Nanoscale

Abstract:
In the world of electronic and magnetic devices, the goal is to get smaller. “The smaller space one bit of information can occupy, the more data you can get into a device and the faster it can operate,” says Yimei Zhu, a senior scientist at the U.S. Department of Energy’s Brookhaven National Laboratory.

Zhu’s group has fabricated patterned magnetic films by depositing magnetic materials such as Permalloy and cobalt in patterns of dots, squares, or ellipses across a surface of nonmagnetic substrates such as carbon or silicon nitride. With each dot measuring about 100 nanometers, or billionths of a meter across, these materials could serve as building blocks for new nanoscale magneto-electronic devices and data storage media.
