We present new results on the magnetic field dependence of the superfluid transition temperatures of theA1 and theA2 phase of3He. TheTA1 transition temperature has been measured up to 15T, theTA2 up to 12T, at the melting pressure. We find thatTA1−TA2 is a linear function of the magnetic field, within the accuracy of the data. The quadrati coefficients ofTA1 andTA2 seem positive and negative respectively, in contradiction to the prediction of the nearly metamagnetic model [1].
