Addition of ferromagnetic particles, hygroscopic water-retaining materials, or other materials can yield a hot melt adhesive which can be activated by microwave heating.
Such anisotropy is not observed for the antiferromagnetic superlattice; as a result, it scatters electrons stronger than the ferromagnetic superlattice and exhibits a higher electrical resistance.
The single domain nature and super paramagnetic behavior of nanoparticles containing ferromagnetic metals could be possibly used for magneto-optical storage media manufacturing.
Another design in development, called racetrack memory, encodes information in the direction of magnetization between domain walls of a ferromagnetic metal wire.
Electrons traveling through the ferromagnetic superlattice interact with it much weaker when their spin directions are opposite to the magnetization of the lattice than when they are parallel to it.
