In everyday magnets -- or ferromagnets
-- such as you might find on fridge doors, the spins of the electrons within align in parallel which imbues the material with its magnetic effect.
explore two mechanisms for all-optical switching in ferromagnets
, modeling ultrafast all-optical switching in synthetic ferrimagnets is then demonstrated by Gerlach et al.

Kittel  established theoretical predictions regarding energetic stability of a single magnetic domain, determining a critical dimension of a particle (typically nanometers for normal ferromagnets
The first step in showing that this may be possible comes from the theory of ferromagnets
. Here systems of spins interact and align parallel only so long as the random effects of heat do not disrupt them too much.
(HMFs) have attracted much attention because of their potential applications in spintronics .
