Definition: spintronics from The Macquarie Dictionary
1.

a branch of electronics in which electron spin, as well as charge, is manipulated to achieve a desired outcome, information being stored as particular spin orientations (up or down).

spintronic adjective


Spintronics

From Encyclopedia of Nanoscience and Society
Spintronics is a contraction of “spin transport electronics,” also known as magnetoelectronics. This refers both to the science of the magnetic energy of electrons and the technology utilizing this phenomenon for purposes of reading, writing, storing, and processing data. In the last half of the 20th century, conventional electronics used the presence and absence of electron charge to express data in the binary logic of ones and zeroes. In contrast, spintronics expresses data by manipulating two weak magnetic states of electrons in metals known as spin up and spin down. Electrons do not literally spin, but point either “up” or “down” in relation to a magnetic field. Within the electronics community, spintronics is widely seen as a potential revolutionary replacement for electron charge-based equipment, enabling the development of smaller, more efficient, and faster computers. The first spintronic devices utilized the physical principle of magnetoresistance. This referred to the changed…

From The Columbia Encyclopedia
spin electronics, or magnetoelectronics, science and technology that harnesses the spin state of electrons in addition to the electrical charge state to store data or perform calculations. The spin of an electron is a property that makes the electron act like a tiny magnet. This property—detected as…
