In a research first that could lead to a new generation of hard drives capable of storing thousands of movies per square inch, physicists at Rice University have decoded the three-dimensional structure of a tornado-like magnetic vortex no larger than a red blood cell.

"Understanding the nuances and functions of magnetic vortices is likely going to be a key in creating next-generation magnetic storage devices," said lead researcher Carl Rau, professor of physics and astronomy. "It's widely believed this technology will support storage densities in the range of terabits per square inch, and our group is equally excited about the potential for magnetic processors and for high-speed magnetic RAM."
