- Descripción
- We use a Migdal-Kadanoff-like renornalization group approach to study the critical behaviour of a semi infinite simple cubic Ising ferromagnet whose (1, 0, 0) free surface contains anisotropic (in spin space) Heisenberg ferromagnetic interactions. The phase diagram presents three phases (namely the paramagnetic, the bulk ferromagnetic and the surface ferromagnetic ones) which join on a multicritical point. The location of this point is calculated as a function of the anisotropy. The various universality classes of the problem are exhibited.
