Definition

1. Noun:
   • The temperature above which a ferromagnetic substance loses its ferromagnetism and becomes paramagnetic: The Curie point is a specific temperature threshold for a given material. Below this temperature, the material exhibits ferromagnetism (permanent magnetism). Above this temperature, the material loses its spontaneous magnetization and becomes paramagnetic, only being weakly attracted to magnets.

Usage Examples

• Noun:
  • The iron's magnetic properties disappear above its Curie point of 770°C.
  • Scientists must consider the Curie point when designing components for high-temperature applications.
  • The transition at the Curie point is a classic example of a phase change in magnetic materials.

Advanced Usage

• "to exceed/pass the Curie point": to heat a material beyond its specific Curie temperature.
  • When the alloy exceeded its Curie point, it ceased to be a permanent magnet.

Variants and Related Words

• Curie temperature (n): A synonymous term for Curie point.
  • The Curie temperature of nickel is approximately 358°C.
• Ferromagnetic (adj): Referring to materials that can exhibit permanent magnetism.
• Paramagnetic (adj): Referring to materials that are only weakly attracted to a magnetic field and do not retain magnetization.

Synonyms

• Curie temperature: The exact synonym for Curie point.

Related Concepts

• Neel temperature: A similar transition temperature for antiferromagnetic materials.
• Magnetic ordering: The alignment of magnetic moments in a material, which changes at the Curie point.
