Phonon and magnon dynamics in CoFe/Pt multilayers

Femtosecond time-resolved spin and phonon wave dynamics were investigated in CoFe/Pt multilayers. Besides the spin and phonon dynamics simultaneous analysis, the high resolution and bandwidth (up to THz) of our approach allowed to estimate magnon’s group velocity and the dynamic exchange coefficient...
