We report on the micromagnetic properties of highly regular hexagonal arrays of Ni nanowires, fabricated by means of electrodeposition in self-ordered porous alumina. Arrays with interpore distances of 65 and 100 nm and pore diameters of 25 and 30 nm are investigated. From hysteresis loops obtained from measurements with a superconducting quantum interference device (SQUID) magnetometer, the switching field Hsw of the nanowires and its deviation ΔHsw is derived. Dynamic micromagnetic modeling using the finite-element method is applied to study the reversal process in an external field. It is shown that starting at the wires' ends, the reversal occurs by means of 180° head-on domain walls propagating along the wire.
