Description
We consider two semi-infinite spin 1/2 Ising media (respectively characterized by the ferromagnetic coupling constants <math>J_1\,\!</math> and <math>J_2\,\!</math> )separated by a spin 1 /2 anisotropic Heisenberg interface (characterized by a ferromagnetic coupling constant <math>J_S\,\!</math>, and by an anisotropy <math>\eta\,\!</math> <math> \epsilon [0,1] \,\!</math> in spin space; <math>\eta =1 \,\!</math> and <math>\eta =0 \,\!</math> respectively correspond to the Ising and isotropic Heisenberg limits). Within a real-space renormalization-group framework, we discuss the full phase diagram; this diagram exhibits, besides the paramagnetic phase, three physically different ordered phases, namely the double-bulk, single-bulk and surface ferromagnetic ones. We also analyze the various universality classes appearing in this problem, and determine, in particular, the existence of a new high-order multicritical point associated with the <math>J_1\,\!</math> = <math>J_2\,\!</math> case.
