Antiferromagnetism

Antiferromagnetism is a type of magnetism found in certain materials where the magnetic moments (tiny magnetic fields) of neighboring atoms align in opposite directions. This means that instead of all pointing the same way like in regular magnets, they cancel each other out. As a result, the material does not exhibit a net magnetic field at a macroscopic level. Antiferromagnetic materials often show unique properties at low temperatures, which can make them useful in various applications, including data storage and spintronics, where the spin of electrons is utilized for information technology.
