Description: Electronic devices that exploit the spin of electrons as well as their charge are poised to overcome
a major hurdle that could signal the beginning of an electronics revolution.
Spintronics, at the interface between magnetism and electronics, is a new field of research in
considerable expansion.
Spintronics, or spin electronics, refers to the study of the role played by electron spin in solid-state
physics, and possible devices that specifically exploit spin properties instead of or in addition to
charge degrees of freedom. For example, spin relaxation and spin transport in metals and
semiconductors are of fundamental research interest not only for being basic solid state physics
issues, but also for the already demonstrated potential these phenomena have in electronic
technology.-Electronic devices that exploit the spin of electrons as well as their charge are poised to overcome

Description: The need for variable speed of an ac induction motor arises in certain industrial applications and
this is often difficult to achieve because induction motors are of fixed speed. The available control techniques
such as variation of supply voltage, variation of number of poles, are characterized by low efficiency and high
maintenance cost. The improvement in power electronics technology through advancements in semi-conductor
electronic devices with increased reliability and reduced cost led to the development of modern solid-state
variable frequency motor drive which is an electronic device capable of controlling the speed of an induction
motor by varying the frequency with increased efficiency, reliability and low maintenance cost Platform: |
