Abstract
Ni-Fe wires with widths > 80μm were prepared by a pulsed laser ablation method, in which the wire was formed by making use of re-ablation of the deposited film. The coercivity is found to increase with decreasing wire width in both the length and width directions. The wires become difficult to magnetize with decreasing wire width. These results are explained in terms of the particular structure of the wire, which is composed of fine particles.
