Nonwetting conditions for coherent quantum precession in superfluid 3He-B

We consider the interaction of the "magnetically superfluid" phase of superfluid 3He−B—the coherently and homogeneously precessing domain (HPD)—with the walls of container. We show that the HPD does not wet the vertical walls, and in a small applied field gradient an extreme nonwetting takes place: the walls are completely coated by the "magnetically nonsuperfluid" phase. The relation of this phenomenon to the experiments with HPD at low temperature is discussed.
