How this entity was disambiguated
This entity first appeared as the object of triple T3093674 — 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: Néel temperature Context triple: [Louis Néel, knownFor, Néel temperature]
-
A.
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.
-
B.
Lifshitz–Kosevich formula
The Lifshitz–Kosevich formula is a key theoretical expression in solid-state physics that describes how the amplitude of quantum oscillations in metals depends on temperature, magnetic field, and electronic properties.
-
C.
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.
-
D.
Peierls transition
The Peierls transition is a phase transition in one-dimensional metals where a periodic lattice distortion opens an energy gap at the Fermi surface, turning the system from a metal into an insulator or semiconductor.
-
E.
Meissner effect
The Meissner effect is the phenomenon in which a superconductor expels magnetic fields from its interior when cooled below its critical temperature, leading to perfect diamagnetism.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
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.
