antiferromagnetic

Thân thiện

In an antiferromagnetic material, the atomic spins align in opposite directions.

Definition

1. Adjective:
   • Relating to antiferromagnetism: Describes a specific magnetic ordering in certain materials where adjacent atomic magnetic moments align in opposite directions, resulting in no net macroscopic magnetization.

Usage

• Adjective:
  • The material exhibits antiferromagnetic ordering below its Néel temperature.
  • This antiferromagnetic phase is crucial for the device's function.

Advanced Usage

• "antiferromagnetic coupling": A specific interaction that causes neighboring magnetic moments to align antiparallel.

  • The thin film relies on antiferromagnetic coupling between its layers.

• "antiferromagnetic resonance": A spectroscopic technique used to study antiferromagnetic materials.

  • The experiment utilized antiferromagnetic resonance to probe the spin waves.

Variants and Related Words

• Antiferromagnetism (n): The physical phenomenon itself, characterized by the antiparallel alignment of magnetic moments.

  • The study focused on the theory of antiferromagnetism.

• Antiferromagnet (n): A material that displays antiferromagnetic properties.

  • Manganese oxide is a classic antiferromagnet.

Synonyms

• Non-ferromagnetic (in a broad, descriptive sense, though less precise as it includes other non-magnetic orders).

Related Phrases
