4-21. Consider a lattice of M equivalent noninteracting magnetic dipoles, u (associated,say, with electron or nuclear spins). When placed in a magnetic field H, each dipole can orientitself either in the same direction, ↑, or opposed to, t, the field. The energy of a dipole is -µHif oriented with the field, and +µH if oriented against the field. Let N be the number of !states and M – N the number of ↑ states. For a given value of N, the total energy isµHN – µH(M – N)=(2N – M)µHThe total magnetic moment I isI=(M -- 2N)µwhere Nis the average value of N for a given M, H, and T. The work necessary to increase Hby dH is -IdH. Find the specific heat C and the total magnetic moment for this system
