Special CMSM Seminar No.306

Transport phenomena play an essential role in designing and engineering materials with tailored functionalities. In this talk, I will highlight our group’s efforts in integrating ultrafast spectroscopy and material engineering to uncover the fundamental mechanisms and new phenomena that govern thermal transport and magnetization dynamics in functional materials. I will share examples, including how we understand and further control thermal transport in (ultra)wide-bandgap perovskites and gallium oxides for power electronics, and how we tailor magnetization dynamics (e.g., damping and magnetic anisotropy) in perpendicular L10-FePd and synthetic antiferromagnets for energy-efficient spintronic applications. If time permits, I will also discuss our discovery of spin-strain coupling in perpendicular Co/Pd multilayers, which provides new pathways for dynamic magnetization control via high-frequency acoustic strains. By combining ultrafast dynamics with materials design, we aim to establish a microscopic understanding of transport and relaxation processes that can ultimately guide the rational design of materials for energy, information, and quantum technologies.
