Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFNeel temperature: The Neel temperature is the temperature above which an antiferromagnetic or ferrimagnetic material becomes paramagnetic which is shown in the figure:
TN : Neel temperature
T < YN : AF state
T > TN : Paramagnetic
\(\chi = \frac{C}{{T - \left( { - \theta } \right)}}\)
Curie point: The critical temperature above which ferromagnetic materials lose their magnetic property is known as Curie temperature.
Curie - Weiss Law: According to Curie - Weiss law, the susceptibility of a ferromagnetic material decreases above a certain temperature called curie temperature and it becomes paramagnetic in nature.
