Definition
Meaning and Definition
A law of physics describing the magnetic susceptibility of a ferromagnetic or paramagnetic material above its Curie temperature, showing that susceptibility is inversely proportional to the difference between temperature and the Curie temperature.
In physics and materials science, the principle describing how certain materials lose their permanent magnetic properties and become paramagnetic above a specific critical temperature. It represents a mean-field approximation for phase transitions.

Common Mistakes When Using “curie-weiss law”
- Misspelling as 'Curie-Weis law', 'Curie-Weiss Law' (incorrect capitalization of 'law'), or 'Curie Weiss law' (missing hyphen).
- Confusing it with the simpler 'Curie's law' which applies to ideal paramagnets.
- Using it in non-scientific contexts.
FAQ
Frequently Asked Questions
Curie's law describes ideal paramagnets, where susceptibility is inversely proportional to absolute temperature (χ = C/T). The Curie-Weiss law modifies this for ferromagnets above their Curie point and some paramagnets, introducing a constant (the Weiss constant, θ), so χ = C/(T - θ).
It is used almost exclusively in condensed matter physics, materials science, and solid-state chemistry for studying magnetic materials, phase transitions, and critical phenomena.
No, it is a mean-field theory. It provides a good first approximation but fails very close to the critical temperature (Curie point) where fluctuations become significant, leading to deviations described by more complex critical exponent theories.
Pierre Curie was a French Nobel Prize-winning physicist who pioneered studies in magnetism and radioactivity. Pierre-Ernest Weiss was a French physicist known for his work on magnetism, notably the molecular field theory (Weiss molecular field) which led to this law.
A law of physics describing the magnetic susceptibility of a ferromagnetic or paramagnetic material above its Curie temperature, showing that susceptibility is inversely proportional to the difference between temperature and the Curie temperature.
Curie-weiss law is usually academic / scientific / technical in register.
Curie-weiss law: in British English it is pronounced /ˌkjʊə.ri ˈvaɪs ˌlɔː/, and in American English it is pronounced /ˌkjʊr.i ˈwaɪs ˌlɔː/. Tap the audio buttons above to hear it.

Mnemonic
Imagine Marie CURIE studying a magnetic piece of metal that goes 'WHEEE!' (Weiss) as it heats up and loses its magnetism – the 'law' describes that moment of transition.
Conceptual Metaphor
A RULEBOOK FOR MAGNETS: Describes the rule that governs how magnets behave when they get too hot and lose their 'magnetic personality'.
