✦ Synopsis

The magnetic signals emitted by a moving A-B interface are calculated using the spin hydrodynamic theory, including both the Leggett-Takagi relaxation and spin diffusion. The B-phase texture is appropriately simplified. Most experimental observations are well accounted for.

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
