At the end of my studies at École Polytechnique (equivalent to the first year of a Master’s program) in France, I had the opportunity to complete a four-month research internship in Professor Otani’s laboratory at the Institute for Solid State Physics (ISSP) of the University of Tokyo. I had long wanted to experience research in Japan, and this internship turned out to be an excellent opportunity, both scientifically and personally.
My project focused on the experimental study of spin–orbit and orbital torques in magnetic multilayers for potential MRAM applications. During this work, I explored the theoretical aspects of spin–orbit interactions while performing experimental measurements and nanofabricating devices. Working through all stages from device fabrication to data analysis was a very enriching experience that allowed me to strengthen both my technical and analytical skills.
I was warmly welcomed by all members of the group. Thanks to the ASPIRE program and the support of the laboratory, all practical and administrative aspects of my stay were taken care of, which made the experience smooth and enjoyable. My supervisor and colleagues supported me daily throughout the internship, and I also had the chance to take part in several social activities that made me feel part of the team.
Beyond the scientific aspects, living and working in Japan was extremely rewarding. It allowed me to discover a new research culture and to collaborate with talented international students and researchers.
Overall, this internship was a truly positive and inspiring experience that strengthened my motivation to pursue a career in research. I am deeply grateful to Professor Otani and the laboratory for their guidance and hospitality.
