Question

The spin magnetic moments of neighbouring atoms of anti-ferro magnetic substance is

Answer 1

Since the options have not been given, I am giving a general answer.

The correct answer could be - Anti-parallel.

The atoms or molecules of the materials which exhibit antiferromagnetism properties have magnetic moments that are usually related to the electron spins. These spins allow alignment in a regular pattern on different sub-lattices with the neighboring spins that are pointing in opposite directions.

In an antiferromagnetic substance, the electrons spins are ordered in an anti-parallel arrangement which has a zero net moment at temperatures that are below the Néel temperature.
