Physicists Trap, Map Tiny Magnetic Vortex: Cell-sized 3-D Structure Could Hold Key For Next-gen ...

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. The findings, published online by Physics Review Letters, were made with a one-of-a-kind scanning ion microscope that trapped and imaged cone-like magnetic vortices on tiny cobalt disks.
