THERMODYNAMIC MEASUREMENT OF THE MAGNETIZATION CURVE OF LIQUID-HE-3 UP TO 200-TESLA

The study of spin polarised liquid He-3 provides new insight in the physics of Fermi liquids. The rapid melting technique offers a way to obtain transiently strongly polarised liquid He-3. We have improved this technique by melting the solid in a silver sinter. This opens the way to experiments on highly polarised liquid (up to 70%) at low temperatures (< 100 mK). The use of this sinter results in a good thermal homogeneity of the sample. We applied our technique to measure the magnetisation curve up to fields as large as 200 T, providing essential information on the magnetism of this Fermi liquid. Other possible experiments are briefly discussed.
