Designating or exhibiting a form of magnetism characterized by an antiparallel alignment of adjacent electron spins in a crystal lattice. Compare with ferrimagnetic.
- In antiferromagnetic materials, the magnetic moments of the adjacent atoms point in opposite directions.
- However, superconducting crystals that have an antiferromagnetic sub-lattice of rare-earth atoms can, and do, exist.
- Novel materials, such as those with heavy fermions that exhibit antiferromagnetic responses, often have electronic properties that cannot be explained by current physics textbooks.
