Low-power spin-wave-based computing

Objective

Downscaling of Si-based microprocessors has considerably increased the amount of heating in computers and other information and communication technology (ICT) devices. As a result, computer servers in big data centres waste more than 90% of the electricity they pull off the grid. High-density electrical currents in microprocessors and interconnects cause excessive warm-up via an effect known as Joule heating. To fulfil future requirements for data transmission and processing rates with low energy consumption, a paradigm shift away from purely charge-based electronics is needed. Recently, post-Si computing with collective spin wave excitations in tailored magnets has been identified as a promising route. Spin waves are transmitted through a magnetic material without the displacement of electric charges (i.e. currents), thus drastically reducing energy consumption and heating. We recently demonstrated that short-wavelength spin waves can be emitted and manipulated by small voltage pulses in ferroelectric-ferromagnetic bilayers. In the ERC PoC project we will use our results to realise an industrially relevant integrated spin wave computing device.
