Abstract

The superfluid ³He-B g-shift has been measured at temperatures above 0.5 mK and at pressures between 1 and 21 bar, at a Larmor frequency of 3.89 MHz. The g-shift is found to be a linear function of the magnetic susceptibility. The Ginzburg-Landau free energy expansion parameter β₃₄₅, and the dipole energy coefficient a are obtained. Deviation from the weak coupling limit with increasing pressure is observed.
