Riga 1:
Dicesi '''punto di Curie''', o '''temperatura di Curie''', quel valore di [[temperatura]] al di sopra del quale un materiale [[Ferromagnetismo|ferromagnetico]] perde alcune delle sue proprietà (quale la corrispondenza non univoca tra campo esterno e magnetizzazione), e si comporta similmente ad un [[Paramagnetismo|paramagnetico]]. Il disordine termico sopra questa temperatura è sufficiente a vincere il contributo energetico dell'interazione di scambio interatomica e la struttura ordinata dei domini magnetici viene quindi distrutta. La [[suscettività magnetica]] segue la legge di Curie-[[Pierre-Ernest Weiss|Weiss]]:
