Magnetization of solid helium three from 0.2T to 11T.

We have used the depression of the sup 3 He melting pressure with magnetic field to determine the magnetization of the ordered solid phases in the T=0 limit from 0.2T to 11T. In the U2D2 phase we find chi = (5.41 +-.08) X 10 sup (-6) cgs, independent of field, while in the CNAF phase we are able to extrapolate the magnetization for the first time to full ferromagnetic alignment at H sub (c2) = (21.7 +- 1)T. This field is of particular importance, as it is the only point in the ordered phases at which the results of mean field theories, used to calculate physical properties from the Hamiltonian, become exact.
