Abstract: The properties of spin-polarized neutron matter are studied both at zero and finite temperature using the D1 and the D1P parametrizations of the Gogny interaction. The results show two different behaviors: whereas the D1P force exhibits a ferromagnetic transition at a density of ρc~1.31fm−3 whose onset increases with temperature, no sign of such a transition is found for D1 at any density and temperature, in agreement with recent microscopic calculations.
