Prof. Liu’s research focuses on synthesis and experimental investigation of nanostructured materials, particularly in nanomagnetism and spintronics, which have potential applications in magnetic recording, low dissipation information storage and nanoelectronics. Current research topics include: Topological spin textures such as magnetic skyrmions and chiral domain walls; Magneto-ionic control of metal/oxide interfaces towards energy-efficient nanoelectronics and neuromorphics; High magnetic anisotropy materials such as L10 FePt for the emerging heat-assisted magnetic recording media; 3D networks for information storage; Low density metallic foams for hydrogen storage and air filtration, etc.
