Spintronics
Spintronics (a portmanteau meaning spin transport electronics), also known as spinelectronics or fluxtronics, is the study of the intrinsic spin of the electron and its associated magnetic moment, in addition to its fundamental electronic charge, in solid-state devices.
Spintronics differs from the older magnetoelectronics, in that spins are manipulated by both magnetic and electrical fields.
