Associate Professor Masamitsu Hayashi
Associate Professor Masamitsu Hayashi of the Department of Physics has received the 17th (FY 2020) Japan Society for the Promotion of Science (JSPS) Prize for his work on "Magnetization dynamics of ferromagnetic nanostructures and physical properties induced by spin-orbit coupling. This prize is awarded to young and mid-career researchers under the age of 45 who are recognized as having achieved particularly outstanding academic results.
The field of "spintronics," which attempts to utilize not only the charge of electrons but also their spin (direction of magnetization) for information processing and storage in computers, is currently the focus of intense research, and Associate Professor Hayashi has continued to lead this field internationally with a succession of pioneering, high-impact results. For example, he has developed a new method for the fabrication of ferromagnetic nanofibers. For example, he has found that when an electric current is applied to ferromagnetic nanowires, a torque caused by spin-orbit interaction is induced, which inverts the direction of magnetization and causes the magnetic walls to move at high speed, and has demonstrated the memory operation of a magnetic shift register using this torque. He also found that the magnitude and sign of the Jarosinski-Moriya interaction, which occurs at the interface between the ferromagnetic layer and the heavy metal layer, can be systematically controlled by changing the material comprising the heavy metal layer, opening up a new field of "spin orbitronics. Furthermore, he showed that BiSb semimetals are promising as new materials that enable current modulation of this interaction and highly efficient control of magnetization.
We would like to congratulate Associate Professor Hayashi on receiving this award and wish him continued success in his future endeavors.
