We report results from a new SQUID-based measurement of the total magnetization change of superfluid 3He at the A-B phase transition, AMAB tΒ°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
The invited talk was given by N. Schopohl. It is an experimental fact that there exists a large range of temperatures and pressures where the A and B phases of superfluid 3He coexist and are almost free of thermal excitations. The phase boundary that forms between the two drastically different bul
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.
