Spin Currents and Antiferromagnets (IMAGE) Norwegian University of Science and Technology Caption Spin current is initiated with an electric field at one end of the material, an antiferromagnet. The spin in the antiferromagnet alternates direction (yellow and blue arrows). The signal spreads as a wave (green arrows) through the antiferromagnet. At the other end of the material, the spin current is transferred to an electric current again Credit Illustration: Kolbjørn Skarpnes/NTNU Usage Restrictions with proper accreditation and only in association with this article License Licensed content Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news releases posted to EurekAlert! by contributing institutions or for the use of any information through the EurekAlert system.
