    Novel Spin-Torque Diode Effect Opening New Possibilities for Ultrafast Information Technology

    A research collaboration led by Assistant Professor Shoya Sakamoto and Associate Professor Shinji Miwa from the Institute for Solid State Physics, along with Professor Satoru Nakatsuji and Project Associate Professor Tomoya Higo from the Graduate School of Science at the University of Tokyo, has made remarkable strides in unlocking the potential of topological antiferromagnetic materials for future telecommunication applications. Their paper, titled "Antiferromagnetic spin-torque diode effect in a kagome Weyl semimetal," has been published in Nature Nanotechnology.
    This study unveils a new spin torque diode effect that remains stable at high frequencies, paving the way for developing ultrafast microwave devices. This advancement is essential for technologies that extend beyond 5G.
