Abstract
A magnetic shield in which all domain patterns and orientations are stable and which are consistently repeated each time the shield is exposed to an initialization field, is disclosed. This is achieved by giving it a suitable shape which ensures that all closure domains can align themselves at a reduced angle relative to the initialization direction while still being roughly antiparallel to each other. Most, though not all, of these shapes are variations on trapezoids.
