Spintronics Seminar Presentation

Classic electronics rely on measuring the tiny electrical charge of electrons but modern electronics named spintronics, which instead based not on electronís charge but on their another fundamental quantum i.e. spin. The devices created through spintronics will be smaller, more robust and faster than the currently used silicon chips and circuits. Electrons spins on its own axis in the atomís nucleus like the Earth revolves around the sun; spin is either up or down, these two spin states will represent the same binary data as the traditional electrons charge represents in 0s and 1s. This provides additional two states, represented by simple currents, so with a mix, a spin can have four possible states representing quantum bits (qubits).Spin can be measured as it generates tiny magnetic fields as when numerous particles have their spin in same direction, they generate magnetic field of same polarity. Various spintronics products which can be introduced like hard drives with 1.2 peta bytes measuring capacity, to increase the rate at which information could be read from hard disk. Others are ipad nano,cell phones and magnetic RAM chips.
