Consider a mole of a material for which each molecule's electron cloud has l = 1,s = 0; there is no spin--orbit coupling. It is placed in an external field of 2 T. For this material, find
(a) its Curie constant,
(b) its magnetic moment at a temperature of 273 K,
(c) the value of x = µBB/kT at a temperature of 1.4 K,
(d) the magnetic moment at a temperature of 1.4 K.
