Abstract
We have measured the absolute thermodynamic magnetization of He-3 in all of its liquid phases while using a new calibration technique which relies on the nuclear paramagnetism over the entire temperature range below 1 K as me asured by Ramm, et al. We have directly measured the temperature dependence separately of the nuclear paramagnetism via NMR and of the total magnetism via our free-surface modulation, technique. We report substantial agreemen t with Ramm, et al. In consequence, we find that the diamagnetism of liquid He-3 is significantly smaller than expected theoretically, a condensed mat ter effect not seen previously. We have also remeasured the magnitude of th e magnetization discontinuity at the superfluid A-B transition and find clo se agreement at saturated vapor pressure with NMR-deduced values from Schol z.
