In the present article we want to describe the main methods and schemes that are used in constructing spintronics elements and devices, and also give a brief analysis of the prospects for their introduction into practice. In our opinion, spintronics devices can replace microelectronic devices in some limited field of technology. First of all, this is the area of registration and processing of small permanent and microwave signals. For such signals, spintronic elements based on metal nanofilms, in comparison with semiconductor elements of microelectronics, have a lower noise level, a high coefficient of thermal stability, and can be used in a higher frequency range. It is most expedient to use the elements of spintronics as high-sensitivity sensors of the magnetic field, in the special devices for recording and storing a data, and for constructing the small-size sources of high-frequency radiation in the gigahertz and terahertz frequency regions.
