How this entity was disambiguated
This entity first appeared as the object of triple T4574460 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Target entity: Curie–Weiss law Context triple: [Curie law of magnetization, isGeneralizedBy, Curie–Weiss law]
-
A.
Curie law of magnetization
The Curie law of magnetization is a fundamental principle in magnetism stating that the magnetic susceptibility of a paramagnetic material is inversely proportional to its absolute temperature.
-
B.
Néel temperature
Néel temperature is the critical temperature below which an antiferromagnetic material transitions from a disordered to an ordered magnetic state.
-
C.
Curie point (Curie temperature)
The Curie point (Curie temperature) is the critical temperature at which a ferromagnetic or ferrimagnetic material loses its permanent magnetism and becomes paramagnetic.
-
D.
Dulong–Petit law
The Dulong–Petit law is an early empirical rule in thermodynamics stating that many solid elements have approximately the same molar heat capacity at high temperatures.
-
E.
Néel relaxation
Néel relaxation is a magnetic relaxation process in which the magnetization of single-domain nanoparticles flips between energy minima due to thermal fluctuations without physical rotation of the particles.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
