Ferromagnetic semiconductor spintronics

摘要

Ferromagnetism in magnetic Ⅲ-Ⅴ semiconductors that can be integrated epitaxially into nonmagnetic heterostructures allows us to explore spin-dependent phenomena previously not accessible in semiconductors. Here, Ⅰ review the properties of ferromagnetic Ⅲ-Ⅴ s and their heterostructures. Prospect of a new class of semiconductor electronics that utilizes both the charge and spin degrees of freedom (semiconductor spintronics) is also discussed.
