The electrical resistivity, $\\rho_{\\rm xx}$, Hall effect, $\\rho_{\\rm xy}$, and specific heat, $C$, are characteristic of an exchange-enhanced Fermi liquid ground state, which develops a slightly anisotropic spin gap $\\Delta \\approx 220\\,{\\rm K}$ below $T_{\\rm N}=88\\,{\\rm K}$. This observation is corroborated by the absence of a Curie dependence in the magnetization for $T\\to0$ reported in the literature.
