Polarization decreases the specific heat of liquid He-3

We report on the first measurements of the polarization dependence of the s pecific heat of liquid He-3. Transient polarizations m df up to 70% were re ached by using the rapid melting technique. The specific heat at 60-100 mK and 27 bars is found to decrease approximately as m(2) the reduction reachi ng at least 30% for m = 70%. These results contradict the nearly localized picture of He-3, and are in agreement with the idea that a large part of th e specific heat is due to spin fluctuations.
