Abstract
The calculation of the texture of superfluid3He-A in a thin slab geometry in the presence of a uniform applied magnetic field is discussed. Dipole-unlocking effects are included and various possible textures are found including one which contains solitons. Such textures can be investigated by including the slab within a torsional oscillator. Solutions for the hydrodynamic equations of3He-A for this situation are obtained by making reasonable approximations and assumptions. A novel feature of the solutions is the existence of oscillatory superflow, which is necessary to achieve mass conservation in an anisotropic superfluid.
