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 ph ysics of Fermi liquids. The rapid melting technique offers a way to ob tain 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 temperat ures (< 100 mK). The use of this sinter results in a good thermal homo geneity of the sample. We applied our technique to measure the magneti sation curve up to fields as large as 200 T, providing essential infor mation on the magnetism of this Fermi liquid. Other possible experimen ts are briefly discussed.
