β¦ Synopsis
New measurements of the static magnetization of 3He-B in contact with a variety of wall configurations are presented and compared with' previous measurements in both A and B phases. At high pressure the data tend toward agreement with resonant-magnetism experiments, while near the polycritical point a large discrepancy between the results of the two methods remains.

Localized magnetic excitations (solitons) in supe~uid 3He are studied theoretically. In the A phase, we determine the dispersion of solitons in both the longitudinal and the transversal configurations, while in the B phase we limit ourselves to the longitudinal soliton in the Leggett cot~guration.

The ringing phenomena in magnetization in the B phase (assumed to be the Balian-Werthamer state) after a sudden application of magnetic fields are analyzed theoretically. Particular" attention is paid to the wall-fixed geometry, where the oscillation is intrinsically nonlinear. The ringing frequency
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
