1. A data storage device comprising:

  • at least one wire of magnetic material having an anisotropy with an easy axis substantially perpendicular to the longitudinal axis of the wire and which is rotated about the longitudinal axis along the length of the wire, wherein the wire is a nanowire or microwire;

    each of the at least one wires having associated therewith;

    a data input element operable to nucleate magnetic domains in an end of the wire, the domains separated by domain walls substantially perpendicular to the longitudinal axis of the wire; and

    a data read-out element operable to detect the magnetisation at an end of the wire; and

    a magnetic field source operable to generate a rotating magnetic field over the length of the at least one wire, the magnetic field rotating in a plane substantially perpendicular to the longitudinal axis of the at least one wire so as to propagate domain walls along the at least one wire.
