ABSTRACT
Spintronics, which utilizes additional spin degree of freedom in electronic systems, is an emerging research subject in the field of electronics due to its distinct advantages of non-volatility, higher speed, lower power consumption, more functionality, and higher density. Some important spintronic devices are introduced in this chapter and a particular emphasis is placed on spin-transfer torque magnetic random access memory and spin field-effect transistor which are considered to have a great potential in applications. Recent progress and remaining challenges on these devices are described.
