The microscopic moments in antiferromagnetic materials have alternated orientation, in contrast to the ones of ferromagnets.
Antiferromagnets are suitable for transporting spin waves over long distances. The microscopic moments in antiferromagnetic materials have alternated orientation, in contrast to the ones of ferromagnets. Smaller, faster, more powerful: The demands on microelectronic devices are high and are constantly increasing. However, if chips, processors and the like are based on electricity, there are limits to miniaturization. Physicists are therefore working on alternative ways of transporting information, such as about spin waves, also called magnons, for example. The advantage would be that they have very little energy loss and can therefore spread over long distances. However, spin waves do not form in just any material, they need certain properties to do so.
