Lattice Dimensionality vs Single Ion Anisotropy

2 Mean or Molecular Field Approximation in Any Dimension and Any Value of 5 

The most general treatment of intermolecular interactions gives rise to the Curie-Weiss law described above (Equation 3.5), allowing intermolecular interactions to be modelled by the parameter, B. This is based on the mean or molecular field approximation, which can be generalised to
