✦ Synopsis

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 re:suits are extrapolated to the infinite system. The critical temperature is found to be TΒ’ = 3.18 + 0.02 and the critical exponents obtained are fl = 0.33 _ 0.02, ~, --1.37 _ 0.04. The specific heat appears to have a cusp with cV = 0.I + 0.03 and c% = 0.1 + 0.1. Remarkable agreement is found with the finite-scaling theory.

Many important classes of problems in materials science and biotechnology require the solution of the Laplace or Poisson equation in disordered two-phase domains in which the phase interface is extensive and convoluted. Green's function first-passage (GFFP) methods solve such problems efficiently by
