Meaning and Definition
A material in which neighbouring magnetic moments (e.g., from atoms or ions) are aligned in opposite directions, resulting in no net macroscopic magnetization in the absence of an external magnetic field.
In condensed matter physics, a substance with antiferromagnetic order, a specific type of long-range magnetic ordering that occurs below a characteristic temperature (the Néel temperature). It can also refer to a sample or device made from such a material.

Common Mistakes When Using “antiferromagnet”
- Confusing it with 'antiferromagnetic', which is the adjective form. E.g., 'It is an antiferromagnetic' (incorrect) vs. 'It is antiferromagnetic' or 'It is an antiferromagnet' (correct).
- Pronouncing it without clear syllable breaks, running 'ferro' and 'magnet' together.
FAQ
Frequently Asked Questions
In a ferromagnet (like iron), atomic magnetic moments align parallel, creating a strong net magnetism. In an antiferromagnet, adjacent moments align in opposite (antiparallel) directions, resulting in zero net magnetism in the ideal state.
Almost exclusively in advanced physics, materials science, or engineering contexts, particularly in research on magnetic materials, spintronics, or quantum computing.
No, it is a very low-frequency, highly specialised technical term. The average person will never need to use or understand it.
Yes. While not obviously magnetic, they are crucial in technologies like spintronic memory (MRAM) due to their stability and fast switching speeds, and are key to understanding high-temperature superconductivity.
