World's Smallest Magnet: One Atom

A view from IBM Research's Nobel prize-winning microscope of a single atom of Holmium, an rare earth element used as a magnet to store one bit of data. Scientists used its scanning tunneling microscope to demonstrate technology that could someday store all 35 million songs on iTunes library on the area of a credit card. (Stan Olswekski for IBM)
