Spin in the slow lane
Article Abstract:
Electrons are thought to transport their charge and spin equally free through metals and semiconductors, but it seems that spin can lag considerably behind charge, as charge and spin are properties of individual electrons. The ability to generate, study and use phenomena such as spin injection, spin currents and spin accumulation, in metals as well as semiconductors, has made it imperative to discover how similar or different spin and charge transport are.

A spin solo
Article Abstract:
Electron spin resonance (ESR) is utilized to rotate a single spin in one of two coupled quantum dots and the effect is detected by measuring variations in electric current flowing through the double dot. The incorporation of ESR into quantum computers would provide them the capacity to solve problems insurmountable to conventional computers.

Spin-torque diode effect in magnetic tunnel junctions
Article Abstract:
A different phenomenon is based on the interplay between spin dynamics and spin dependent transport arising from unusual diode behaviour. The behaviour is different from conventional semiconductor diode and forms the basis of a nanometre-scale radio frequency detector in telecommunication circuits.
