A brief intro to altermagnetism

A Brief Introduction to Altermagnetism

Experiments have only recently confirmed the existence of this type of magnetic material, but it's already making waves.

By Jennifer Newton, 2025-10-27T13:34:00+00:00. The author notes that altermagnets were unfamiliar until reading about them, but quickly grabbed attention.

Our understanding of ferromagnetism dates back thousands of years, with early civilizations observing it in naturally magnetized minerals like lodestone (magnetite). In ferromagnetic materials, the intrinsic magnetic dipole moments align in parallel, producing a net magnetic field.

Meanwhile, antiferromagnetism occurs when neighboring magnetic dipole moments align in opposite directions, canceling each other out.

Altermagnets might play a role in the field of magnonics.

Author's summary: Altermagnetism is a newly confirmed magnetic material.
