Antiferromagnetic refers to magnetic materials which exhibit an inherent magnetic ordering. However, sometimes it might become essential to use alternative terms to express the same meaning. In such cases, there are several synonyms for the word "antiferromagnetic" that can be used. For instance, the term "antiparallel magnetization" is often used to describe materials that exhibit antiferromagnetic properties. Additionally, "antimagnetic" and "antiferroic" are also terms that are sometimes used to refer to materials with antiferromagnetic characteristics. Other synonyms include "spin-compensated" and "AFM". Overall, the choice of synonym would depend on the context and nature of the subject matter.
