ON THE SPLITTING OF THE SUPERFLUID A-PHASE OF HE-3 IN HIGH MAGNETIC-FIELDS

We present new results on the magnetic field dependence of the superfl uid transition temperatures of the Al and the Az phase of He-3. The TA (1) transition temperature has been measured up to 15T, the T-A2 up to 12T, at the melting pressure. We find that T-A1 - T-A2 is a linear fu nction of the magnetic field, within the accuracy of the data. The qua dratic coefficients of T-A1 and T-A2 Seem positive and negative respec tively, in contradiction to the prediction of the nearly metamagnetic model [1].
