Magnons vs electrons: A new spin on computer processing

Phys.org  December 1, 2021 An international team of researchers (USA – UC Berkeley, Japan) believe that to surpasses the limits of Moore’s Law magnons can be harnessed to carry information. Since the electrons themselves remain stationary as magnons pass through them, there is no heat to be dissipated, the major limiting factor in Moore’s Law. Magnons carry spins faster and with lower heat dissipation than electrons. They are starting with heterostructures of Mott insulators and heavy metals that will enable them to add and remove spin in the Mott insulator. They are fabricating a prototype Topological Magnon Transistor (TMT) in […]
