Magnetic domain patterns in a zigzag nanowire

Nanowires of modulated widths are potential candidate for the study of shape dependence of nanoscale magnetic properties. A study of magnetic domain arrangement in zigzag nanowires fabricated by self-assembly of nanoparticles and etching technique is presented. Thin necks in the zigzags create an anisotropy which allows domains to distribute between adjacent triangles. Magnetic force microscopy shows unique magnetization patterns for different orientations of the applied field.
