Abstract: The equilibrium properties of the classical f.c.c. Heisenberg ferromagnet are studied by Monte- Carlo techniques for small finite systems. Using the asymptotic dependence on the system size the results are extrapolated to the infinite system. The critical temperature is found to be Tc = 3.18 ± 0.02 and the critical exponents obtained are β = 0.33 ± 0.02, γ = 1.37 ± 0.04. The specific heat appears to have a cusp with α′s = 0.1 ± 0.03 and αs = 0.1 ± 0.1. Remarkable agreement is found with the finite-scaling theory.
