Spintronics can
be fairly new term for you but the concept isn't so very exotic .This technological
discipline aim to exploit subtle and mind bending esoteric quantum property of
electron to develop a new generation of electronics devices. The ability to exploit
spin in semiconductor promise a new logical devices as spin transistor etc with
enhanced functionality higher speed and reduction power conception and might have
a spark revolution in semiconductor industry. so far the problem of injecting
electron with controlled spin direction has held up the realization of such spintronics Spintronics
is an emergent technology that exploits the quantum propensity of the electrons
to spin as well as making use of their charge state. The spin itself is manifested
as a detectable weak magnetic energy state characterised as "spin up"
or "spin down".
Conventional
electronic devices rely on the transport of electrical charge carriers - electrons
- in a semiconductor such as silicon. Device engineers and physicists are now
trying to exploit the spin of the electron rather than its charge.
Spintronic-devices
combine the advantages of magnetic materials and semiconductors. They are expected
to be non-volatile, versatile, fast and capable of simultaneous data storage and
processing, while at the same time consuming less energy. Spintronic-devices are
playing an increasingly significant role in high-density data storage, microelectronics,
sensors, quantum computing and bio-medical applications, etc.
