Daima Kobayashi (a second-year master's student at the Graduate School of Science and Technology, Keio University), Tomohide Yoshikawa (graduated from the Faculty of Science and Technology in March 2017), and Professor Yukio Nozaki; Assistant Professor Ryo Iguchi (at the time of research; currently a researcher at the National Institute for Materials Science) and Professor Eiji Saitoh of the Institute for Materials Research, Tohoku University; and Researcher Mamoru Matsuo (at the time of research; currently a researcher at the Advanced Institute for Materials Research, Tohoku University) and Center Director Sadamichi Maekawa of the Advanced Science Research Center, Japan Atomic Energy Agency, have succeeded in generating a "spin current"—a flow of magnetism carried by electrons—by injecting sound waves into copper. This new method of spin current generation demonstrated in this research is expected to lead to the realization of energy-saving magnetic devices that do not require magnets or precious metals.
The results of this research were published online in the American Physical Society's journal "Physical Review Letters" on August 16 (local time). It was also selected as an Editors' Suggestion, which highlights articles of particular importance and interest.
