Quantum Theory of Magnetism Springer
The classical theory of paramagnetism is just like the theory of the dielectric constant we showed you in Chapter 11. One assumes that each of the atoms has a magnetic moment $\FLPmu$, which always has the same magnitude but which can point in any direction. In a field $\FLPB$, the magnetic energy is $-\FLPmu\cdot\FLPB=-\mu B\cos\theta$, where $\theta$ is the angle between the moment and the...

So we can use perturbation theory to calculate the change in the energy of the system due to the magnetic perturbation. Using second order perturbation theory to get terms upto second order in H: where the energy change E n due to the magnetic field is: Combining (1) and (2) we get; to second order in H From this

- Here we report the theory developed by Weiss which is very similar to the one used for paramagnetism. In fact, the main difference stays in the postulation of an additional magnetic field w whose non magnetic (Maxwellian) origin is not investigated.
- The theory of paramagnetism, originally developed by Langevin (1905) and extended by Weiss (1907) to include ferromagnetics, led to expressions giving the variation of magnetization with temperature above and below the Curie point. These proved of great value in correlating experimental results, and
