Synthetic antiferromagnets are carefully engineered magnetic materials made up of alternating ferromagnetic layers with oppositely aligned magnetic moments, separated by a non-magnetic spacer. These materials can display interesting magnetization patterns, characterized by swift changes in the behavior of magnetic moments in response to external forces, such as radio frequency (RF) currents.



Summary

Synthetic antiferromagnets (SAFs) are layered materials composed of ferromagnetic layers with antiparallel magnetic alignment, separated by non-magnetic spacers. This unique structure allows SAFs to exhibit complex magnetization dynamics. A key characteristic is their rapid response to external stimuli like radio frequency (RF) currents, leading to quick changes in the orientation of their magnetic moments. This responsiveness makes SAFs promising for various applications requiring high-speed magnetic switching and manipulation.
