Implication

Experimental analysis demonstrates terahertz-driven coherent magnetization dynamics in a cobalt-platinum multilayer, highlighting new prospects for high-speed spintronics.

Key Points

Terahertz pulses drive ultrafast demagnetization and coherent magnetization dynamics within cobalt-platinum labyrinth domain networks.
Local magnetization oscillations emerge at the 2.5 THz fundamental frequency, following a temporal lag explained by time-dependent damping.
Correlated dynamics across domain and domain-wall contributions highlight the potential of nanoscale terahertz spin control in spintronics.
