Manipulation of magnetism with picosecond current pulses

Join a pioneering joint-PhD project focused on using picosecond-wide electrical current pulses to control magnetization in novel magnetic heterostructures. Building on groundbreaking work at IJL [1] and Tohoku University [2,3], you will explore: -Antiferromagnetic materials (e.g., Mn₃Sn) for ultrafast memory and computing applications. -Size-dependent effects in ferro-, ferri-, and antiferromagnets, addressing scalability and efficiency in next-gen spintronic devices. -Alternate spin-orbit torque geometries (x-, y-, z-types) in the picosecond regime, aiming to enhance speed and efficiency in magnetic memory technology. This project combines cutting-edge pulse generation and advanced magnetic characterization, from the two groups at the University of Lorraine (France) and Tohoku University (Japan). The student will be trained on a femtosecond laser bench, and learn extensively about aspects such as spintronics, ultrafast optics, electronics material growth and sample fabrication. During his PhD he will establish a new collaborative research line between the two universities, and will spend time in both labs. Check attached PDF file for more details. References [1] K.
