Ultrafast Dynamics in Hexagonal HoMnO3 Studied by Femtosecond Spectroscopy
碩士 === 國立交通大學 === 電子物理系所 === 97 === We studied the ultrafast dynamics in hexagonal HoMnO3 by pump-probe system and time-resolved MOKE system with different polarization pump beam (linear, left circular, right circular polarization), various temperatures, and magnetic field. The disorder, disorder ti...
