We apply the thermal boson expansion which has been presented in refs. [1][2][3] to the Heisenberg isotropic antiferromagnet, submitted to an external field. Considering only spin waves with wave vectors up to a certain cut-off, the magnetization and the principal susceptibilities are calculated. Th

The method of thermal boson expansion [1] is extended to the Heisenberg model with spins S/> 1 and applied to the ferromagnetic insulators EuO and EuS. Taking in the momentum space an adequate cut-off, which is almost independent of the spin, a good guess of the critical temperature is made. The te
