    Abstract

    Reproducible measurements of critical velocities for flow-induced reversible and irreversible textural transitions in rotating 3He-A were performed. Control of the texture was gained by placing 3He-A in a slab of thickness D. This also imposed a length scale D. Magnetic field was applied to control the vortex soft core size and to introduce a pair of domain walls on demand. Overall, significant results were obtained.
