Abstract
Direct nuclear demagnetization has been made for two-dimensional solid 3He adsorbed on graphite. The lowest temperature is estimated to be about 10 µK from the observed magnetization of the paramagnetic solid 3He. The deviation from, ideal behavior is explained by a simple heat flow model.
