Using magnetic effects in electrons for a hundredfold reduction in the power consumption of future chips

Nanowerk August 15, 2023
As electronic devices shrink, they become more powerful, use more energy and produce more heat. A consortium of researchers is working under an EU funded HORIZON project, “SPIDER” (Spin Wave Computing for Ultimately-Scaled Hybrid Low-Power Electronics), to investigate how changes to the magnetic properties of semiconductors could achieve a hundredfold reduction in the power consumption of computer chips. They have developed a computer system that combines magnonics with conventional computing technology with its standard semiconductor systems. They produced an interface between the conventional computer and a spin wave circuit made from sapphire or gadolinium gallium garnet (GGG). It operated at frequencies of up to 16 GHz with more than a hundred channels using almost identical wiring lengths. The project is scheduled to run from 1 December 2022 to 31 May 2026… read more.
