Every substance has a magnetic properties associated with it. The origin of these properties lies in the electron. Each electron in an atom behaves like a tiny magnet. Its magnetic moment originates from two types of motion (i) its orbital motion around the nucleus and (ii) it spin around its own axis.
One the basis of their magnetic properties, substances can be classified into five categories and from them, antiferromagnetism is the answer.
Substance like MnO showing antiferromagnetism have domains structure similar to ferromagnetic substance, but their domains are oppositely oriented and cancel out each other’s magnetic moment.
