Magnetic Vortices
Magnetic spirals occur in nanometer-thin magnetic layers.  The magnetization of the nucleus of these spirals can be switched at lightning speed when a short electric pulse is applied – a process shown here in this computer simulation.  Structures such as these could function as bits in miniaturized data storage systems of the future.
