Professor Atsufumi Hirohata (PI)

Research Interests

Dr Atsufumi Hirohata is a Professor in Nanoelectronics since October 2014 after joining the Department of Electronics (now Department of Electronic Engineering) in September 2007. He has over 15 years of experience in spintronics, ranging from magnetic-domain imaging to spin-current interference. Before coming to York, he was a researcher at RIKEN, a Japanese governmental research institute, for over two years, where he designed a spin-current interference device, which can be used as a spin operation in a spintronic three-terminal transistor. He was before working as a postdoctoral researcher at Tohoku University, and successfully fabricated a perfectly ordered epitaxial full-Heusler alloy films, which was the first report to their knowledge and was acknowledged by several awards. He also worked as a postdoctoral associate at Massachusetts Institute of Technology, where he demonstrated basic function of a phase-change memory, which has been recently released in a market by Intel. He received his PhD in Physics at the University of Cambridge in 2001 and then served as a research associate at the Cavendish Laboratory to complete his study on spin detection of optically pumped spin-polarised electrons in a semiconductor with using a ferromagnetic overlayers, which attracted great interests, resulting a few invited talks and papers. He was originally graduated from Keio University for his BSc and MSc studies in Physics.

During this time he has secured seven major research grants with a total value of GBP 13M. He has maintained a high level of publication throughout his career having published 132 refereed works plus 2 work in press, and 5 book chapters (134 publications in total). These include Nature Materials, Advanced Functional Materials, Nature Communications, Physical Review Letters, Scientific Reports and Applied Physics Letters. He has also filed 35 patents (including 12 pending). His H-index is currently 23 (24) and my work has been cited 1,512 (2,215) times in total by Thomson Reuter Google Scholar). Full list of publications can be found at Publications page.

He has also given over 100 invited talks since 2007 including at prestigious meetings such as an MMM conference in USA, and UK-Korea workshop on New Trends in Magnetism in Korea, an UK-Japan workshop on Organic Electronics in London and the Seagate Conclave in Belfast and at other leading centres such as the Naval Research Laboratory and Argonne National Laboratory in the USA. Full list of presentations can be found at Presentations page.

His present research interests include fabrication of a spin operator and growth of a half-metalic film. Further details can be found in research.
