Multiturn counter using magnetic domain wall conductors wound in the manner of closed loops

Revolution counter, comprising magnetic domain wall conductors which are wound each as a loop in a form of a spiral configured to be closed and are situated essentially in a plane, wherein in a connecting region inner and outer loop section ends of the loop of a first magnetic domain wall conductor are combined and bridged by a second magnetic domain wall conductor which is connected to the inner and outer loop section ends of the loop of the first magnetic domain wall conductor with a gap therebetween, the gap creating a local interruption of the first magnetic domain wall conductor, the gap being provided with such a width that, during a movement of a domain wall of a first domain conductor section of either the first or the second magnetic domain wall conductor, a stray field is generated therein and, in a direction the movement, downstream from the gap, results in nucleation of a domain wall in a subsequent domain conductor section, a mean width of the gap being set to be less than a thickness of the magnetic domain wall conductors and adjoining domain conductor sections of the first and second magnetic domain wall conductors being encompassed by a non- magnetic layer in a region of the gap.
