Bulk /sup 3/He-A in a uniform relative superflow is known to deform with increasing parallel magnetic field from a uniform structure to a helical one. This latter texture becomes unstable at a critical field, beyond which the system exhibits runaway nonlinear growth. Subsequent behavior depends on the specific external configuration. In a torus, the texture apparently evolves into a stable wide-angle helix with a reversed and largely quenched superflow. In an applied heat flow, the texture instead oscillates periodically but anharmonically.
