Abstract
⺠We study the classical Heisenberg ferromagnet in an external magnetic field. ⺠We use the two-time classical Green's function technique. ⺠Our aim is to extend the quantum Callen formula for the magnetization. ⺠We compare our predictions with exact numerical results. ⺠The new formula provides accurate predictions in a wide range of temperatures.
