Magnetization of SolidHe3through the Nuclear Ordering Temperature

We have measured the static nuclear magnetization of solid ${}_{}{}^3{}_{}{}^{}\mathrm{He}$ as a function of temperature and molar volume through its nuclear ordering temperature. Below 5 mK the magnetization increases with decreasing temperature more rapidly than the Curie-Weiss behavior displayed at higher temperatures. At $T_S$ it decreases rapidly to 40% of its maximum value and becomes temperature independent at the lowest temperature we measure. $T_S$ decreases with decreasing molar volumes.
