Curie constant

Curie's constant is

C = \frac{N \mu^2}{k_B},

where N is the number of magnetic moments, μ is an individual magnetic moment and kB is Boltzmann's constant. It comes from Curie's Law, which is the relationship between magnetic susceptibility and temperature of a paramagnetic material

\chi = \frac{C}{T}.

This equation was first derived by Pierre Curie (Marie Curie's husband.)

Because of the relationship between magnetic susceptibility χ, magnetization M and applied magnetic field H:

\chi = \frac{M}{H},

this shows that for a paramagnetic system of non-interacting magnetic moments, magnetization M is inversely related to temperature T (see Curie's Law).
