ABSTRACT
Magnetic solids form a special class of materials, and in this chapter we again conˆne our attention to the thermodynamics of ideal paramagnetic materials that obey Curie’s law. e value of the Curie constant obtained in Chapter 5 and the expression derived there for the speciˆc heat of a paramagnet are used in the discussion. e Maxwell relations, derived for gases in Chapter 7, are extended to paramagnets to facilitate the analysis of magnetic processes in these systems. Magnetic order that is found in nonideal magnetic systems, where interactions between spins are important, is dealt with in Chapter 17.
