Due to the specific discrete symmetry of the superfluid 3He-A2 order parameter, linear singularities can exist which are characterized by a quarter-integer quantum of superflow velocity circulation. Some consequences of this observation are analyzed. ## O = ½[(A r + A,)al(Z) + i(AT --A,)d2(z)]e i'p
We report results from a new SQUID-based measurement of the total magnetization change of superfluid 3He at the A-B phase transition, AMAB t°tal. We used a simple first-principles calibration technique. At low fields -0.03 T, our data agree with past measurements, verifying the longstanding discrepa
