Problem

Show that the Curie constant for an ensemble of

N

spin-1 particles of mass

m

and charge

q = -e

immersed in a uniform magnetic field

\mathbf{B} = B\mathbf{k}

is given by

C = \frac{2N\mu^2}{3k_B}

where

\mu = ge\hbar/2mc

. Compare this value for

C

with that for an ensemble of spin-

\frac{1}{2}

particles, as determined in Example 5.6.
