A shock of currents: a helical non-magnetic semiconductor becomes a magnet by electrical currents

October 16(Mon), 2017

Researchers of Tokyo University of Science and Okayama University demonstrated magnetization is induced on elemental tellurium, a non-magnetic helical-structured semiconductor via magnetoelectric effect. The team consisting of Tetsuya Furukawa, Assistant Professor, Yuri Shimokawa, student (at the time of the research), and Tetsuaki Itou, Associate Professor at the Department of Applied Physics, Tokyo University of Science, and Kaya Kobayashi, Associate Professor at the Research Institute for Interdisciplinary Science, Okayama University detected the magnetization induced by currents using the technique called nuclear magnetic resonance, a common technique used in MRI.

This research result was published in a U.K. scientific journal entitled Nature Communications, dated October 16th.
