Abstract

360˚, 540˚ and other complex transverse domain walls have been created in narrow Co wires connected to injection pads by cycling a magnetic field perpendicular to the wire length. The composite walls, formed by impingement of 180˚ transverse walls of alternating chirality, are stable over a wide field range. The structure of the walls observed at remanence by scanning electron microscopy with polarization analysis and magnetic force microscopy is in good quantitative agreement with the prediction of micromagnetic simulations.
