Magnon spintronics
- Focus issue:
- June 2015 Volume 11 No 6 pp437-516
Although mostly based on electron charges, information processing technologies also make use of the electron spin. This Focus surveys the field of magnon spintronics, which harnesses quantized spin waves – magnons – as the carriers of spin currents.

Magnons provide a route for information-processing technologies that are free from charge-related dissipations. Advances in the manipulation of magnons, and the conversion to charge currents, bring magnon-based computing closer to realization.

The periodic modulation of the magnetic properties of magnonic crystals controls the flow of spin waves. An optical method is now shown that can produce such modulations by heating, which can be reprogrammed during operation.
