DIAMAGNETIC MAGNETIZATION OF NORMAL AND SUPERFLUID HE-3

The absolute thermodynamic magnetization of liquid He-3 has been measu red from 0.5 mK - 100 mK at saturated vapor pressure. The measurement uses a SQUID magnetometer and a simple displacement technique to refer ence the total magnetization of the liquid to an absolute vacuum level . Because the nuclear paramagnetic magnetization equilibrates on a tim e scale long compared to that of the core diamagnetic magnetization, w e are able to separate these two signals throughout much of the normal Fermi liquid regime. The diamagnetic component dominates the paramagn etic over the entire temperature range.
