The thermodynamic properties of a classical d-dimensional spin-S Heisenberg ferromagnet, with long-range interactions decaying as r-p and in the presence of an external magnetic field, is investigated by means of the spectral density method in the framework of classical statistical mechanics. We find that long-range order exists at finite temperature for d<p<2d with d≤ 2 and for p>d with d>2, consistently with known theorems. Besides, the related critical temperature is determined and a study of the critical properties is performed.
