We found a Curie-Weiss (CW) behavior for $\\chi$(T) with a ferromagnetic $\\Theta = 446(5)$ K and $\\mu_{eff} = 4.72(9) \\mu_{B}/f.u.$, this being lower than that expected for either $Fe^{3+}(5.9\\mu_{B})$ or $Fe^{2+}(4.9\\mu_{B})$ ions. The ESR g-factor $g = 2.01(2)$, is associated with $Fe^{3+}$. We obtained an excellent description of the experiments in terms of two interacting sublattices: the localized $Fe^{3+}$ ($3d^{5}$) cores and the delocalized electrons.
