摘要：

We report results of an investigation of the growth of He-3-B into supercooled, magnetized He-3-A. The B-phase growth was observed magnetically, with the difference between A- and B-phase susceptibilities generating signals in SQUID magnetometers. The form of the magnetization signal associated with the moving interface evolved radically with increased supercooling, indicating that the rapidly moving interface is no longer a simple boundary between equilibrium B phase and metastable equilibrated A phase. Magnetization changes were observed to travel through the superfluid as fast as 800 cm/s. Several features of the measurements can be explained by a model based on magnetization transport by a critical-velocity-limited spin supercurrent. Other features of the data remain unexplained.
