Abstract
The critical behaviour of an anisotropic n-vector model with pure single-component or Ising-like coupling is studied. The non-interacting spin components are integrated over, and the resulting single-component, reduced hamiltonian represents the gaussian model for n= infinity and the Ising-Ginzburg-Landau-Wilson model for finite n. For large n one finds T c(n)-Tc( infinity ) varies as 1/n, while the susceptibility behaves as chi approximately t-1X(1/ntphi), with t=T/Tc(n)-1 and phi =1/2(4-d).
