Spintronics is an emerging field of nanoscale electronics involving the creation, manipulation and detection of electron spin. Over the past two decades, there have been tremendous studies to discover fundamentally new spin-related phenomena. Several intriguing phenomena, such as spin Hall effect, spin transfer torque and spin seebeck effect, have been indeed discovered. Spintronics has also unique fields of applications such as magnetic data storages or logics. Examples range from hard disk drive to magnetic random access memory or racetrack memory. All of these successes are based on understanding of spin transport and dynamics in magnetic materials. This talk will briefly review the recent progress of spin dynamics in the field of spintronics. In particular, we will discuss our finding on the dynamics of topological spin structure and antiferromagnetic spin dynamics.
