Abstract
Magnetic device comprising at least one thin layer of a magnetisable material which has a preferred direction of magnetisation substantially at right angles to the surface of the layer. Magnetic domains are produced by a magnetic field which is situated substantially in the plane of the layer and does not change direction and enables similar domains to be produced. The domains are there after maintained by a field normal to the layer. A domain guide structure may also be provided on the layer to move the domains.
