“All-optical Control of Magnetization in Nanostructures” Committee: Prof. Yongmin Liu (Advisor) Prof. Don Heiman Prof. Nian X. Sun Abstract: The switching of magnetization by a femtosecond laser within several picoseconds has recently gained substantial attention, because it promises next-generation, energy-efficient, and high-rate data storage technology. One of the most intriguing demonstrations is the helicity-dependent switching […]
