Ferrimagnetic resonance of Mn3Si2Te6
ORAL
Abstract
Spin dynamics has been proven to be an effective way to explore the nature of magnetic materials. Recently, unconventional colossal magnetoresistance is observed in van der Waals ferrimagnet Mn3Si2Te6, where the chiral loop-current state is indicated to play an important role.
In this work, we present our recent study of ferrimagnetic resonance of Mn3Si2Te6. We studied temperature and magnetic-field dependence of ferrimagnetic resonance mode in various configuration of magnetic field and thickness. Also, transport properties under the ferrimagnetic resonance may reflect the scattering induced by spin dynamics. This study helps us to understand the underlying mechanisms of such unconventional colossal magnetoresistance and the spin dynamics.
