Spin wave signals used in computing boosted more than 5,000 times in Z-shaped path approach

A research team from Tohoku University, Shin-Etsu Chemical Co., Ltd., and École Polytechnique Fédérale de Lausanne (EPFL) has invented a new way to efficiently guide spin waves around sharp corners with minimal loss-representing an exciting discovery for energy-efficient computing. Using a two-dimensional magnonic crystal-a copper (Cu) film with a hexagonal array of tiny holes placed on a magnetic garnet film-the team showed through calculations that spin waves travel along a Z-shaped path mo...
