Spin conversion on the nanoscale

Spins can act as mediators to interconvert electricity, light, sound, vibration and heat. Here, we give an overview of the recent advances in different sub-disciplines of spintronics that can be associated with the developing field of spin conversion, and discuss future prospects. Spins can act as mediators to interconvert electricity, light, sound, vibration and heat. This Progress article gives an overview of the recent advances associated with nanoscale spin conversion.
