Scientists are a long way off from a complete understanding of the interactions and behaviors that govern nanomagnets — magnets on the scale of a billionth of a meter. However, a groundbreaking new study helps answer some basic questions about nanomagnets, which could one day revolutionize (and drastically miniaturize) computer data-storage systems, telecommunications devices, and other technologies that rely on magnets.
