Few books exist that cover the hot field of second-generation spintronic devices, despite their potential to revolutionize the IT industry.Compiling the obstacles and progress of spin-controlled devices into one source, Spintronic Materials and Technology presents an in-depth examination of the most recent technological spintronic developments. Featuring contributions from active researchers and leading experts, the book chronicles the main research challenges in spintronics. It first depicts the different classes of materials systems currently under investigation for use in spintronic devices. The contributors also address issues concerning the operation of spintronic devices, such as the new principle for future devices that use spin-polarized current. This promises to enable switching of individual spin components of the device while avoiding crosstalk at the nanoscale. The book concludes with descriptions of both Si and III-V semiconductor-based spin transistors and the integration of spin technology with photonics. The second-generation spintronic devices discussed in Spintronic Materials and Technology will not only improve the existing capabilities of electronic transistors, but will enable future computers to run faster and consume less power.
