M. Bravin et al., MEASUREMENTS OF THE NUCLEAR MAGNETISM OF LIQUID 3HE UP TO 25 TESLA USING A TORQUE MAGNETOMETER, Physica. B, Condensed matter, 194, 1994, pp. 745-746
Precision measurements of the magnetisation curve of liquid He-3 provi
de a way to test the various microscopic theories of this Fermi liquid
. In this aim, we have developed a magnetometer, which measures a torq
ue due to a He-3 sample in a magnetic field gradient. We used this dev
ice in resistive and hybrid magnets at Grenoble and Nijmegen up to fie
lds of 25T and at temperatures down to 50 mK. We present preliminary r
esults on the field and temperature dependence of the magnetisation.
