Spin transfer torque is the transfer of the spin angular momentum from conduction electrons to the magnetization of a ferromagnet and enables the manipulation of nanomagnets with spin currents rather than magnetic fields,» explained Gyung - Min Choi, who recently completed his PhD in materials science and engineering at Illinois.

Complex nanomagnet arrays with exotic geometries can be designed and fabricated to exhibit desired physical phenomena and subtle effects. (sciencedaily.com)
Current magnetic storage and recording devices, such as computer hard disks, contain nanomagnets with two polarities, each of which is used to represent either 0 or 1 — the binary digits, or bits, used in computers. (sciencedaily.com)
