    Default Spintronics - Quantum Information, Computers, The future?


    The term Spintronics refers to the exploitation of electron spin as an additional degree of freedom with which to control the motion of an electron. Many observers believe that Spintronics will deliver future generations of low-power electronics, while providing the most feasible route to the realization of a quantum computer. Many device concepts have been proposed within semiconductor spintronics, yet fundamental problems remain in the development of room temperature ferromagnetic semiconductors and reliable transfer of spin-polarized electrons to and from other ferromagnetic materials. In contrast, room temperature metal-based spintronics is now well established, with Albert Fert and Peter Grünberg receiving the 2007 Nobel Prize in Physics for the discovery of the Giant Magnetoresistance effect, which has proved to be of enormous economic significance with its application to disk drive sensor technology. More recently the discovery of spin transfer torque (STT) has presented a new challenge within spintronics. By controlling non-local spin populations it seems feasible to develop an entirely new generation of electronics in which the transfer of spin angular momentum associated with an electrical current is used ot control the state of ferromagnetic components within the circuit.

    @-shinobi-, no problem.. glad to share the things I've encountered. hehehe

    @cromagnon, murag dili tingali ta ka-abot sa quantum computers.. spintronic devices ra tingali.. pero kung matinoud tong naa sa usa ka thread nga elixir of life, aw, basin pa diay.. hehehehe

    dont u just wish you could travel into the future (say... 300yrs frm now) and see how things are.. imagine the technology!!
