This review compiles results of experimental and theoretical studies on thin films and
quantum structures of semiconductors with randomly distributed Mn ions, which exhibit …

Spintronics, or spin electronics, involves the study of active control and manipulation of spin
degrees of freedom in solid-state systems. This article reviews the current status of this …

Although microscopic laws of physics are invariant under the reversal of the arrow of time,
the transport of energy and information in most devices is an irreversible process. It is this …

Electrons have a charge and a spin, but until recently, charges and spins have been
considered separately. In conventional electronics, the charges are manipulated by electric …

This review article first presents a summary of current understanding of the magnetic
properties and intrinsic ferromagnetism of transition-metal (TM)-doped ZnO films, which are …

The recent development of MBE techniques for growth of III–V ferromagnetic
semiconductors has created materials with exceptional promise in spintronics, that is …

Spin electronics (spintronics) exploits the magnetic nature of electrons, and this principle is
commercially applied in, for example, the spin valves of disk-drive read heads. There is …

We show that the accumulation of spin-polarized electrons at a forward-biased Schottky
tunnel barrier between Fe and n-GaAs can be detected electrically. The spin accumulation …

Spintronics is an emergent interdisciplinary topic for the studies of spin-based, other than or
in addition to charge-only-based physical phenomena. Since the discovery of giant …

Injecting spins into a semiconductor channel and transforming the spin information into a
significant electrical output signal is a long-standing problem in spintronics. This is the …
