Spintronics ,also identified as spinelectronics or fluxtronics, is the study of the intrinsic spin of the electron and its related magnetic moment, in addition to its fundamental electronic charge, in solid-state devices.Spintronics varies from the older magnetoelectronics, in that spins are operated by both magnetic and electrical fields.
In a solid the spins of several electrons can act collectively to affect the magnetic and electronic properties of a material, for example providing it with a permanent magnetic moment as in a ferromagnet.In numerous materials, electron spins are equally present equally in the up and the down state, and no transport properties are dependent on spin. A spintronic device needs generation or manipulation of a spin-polarized populace of electrons, resultant in an excess of spin up or spin down electrons
The simplest method of producing a spin-polarised current in a metal is to pass the current through a ferromagnetic material. The maximum applications of this effect involve huge magneto resistance (GMR) devices. A typical GMR device contains of at least two layers of ferromagnetic materials divided by a spacer layer. When the two magnetization vectors of the ferromagnetic layers are allied, the electrical resistance will be lesser (so a higher current flows at constant voltage) than if the ferromagnetic layers are uninitialized. This creates a magnetic field sensor.
