Explain spintronics devices and give their applications. Or Explain, what is spintronic

Ans. A very important device based on the GMR effect is called the spin valve is shown in fig. 4.1 0. Here, one of the ferromagnetic layers has a .fixed (pinned) magnetization direction, due to the presence of the antiferromagnetic layer, and the other ferromagnetic layer magnetization [...]
