Fabrication of Magnetic Nanowires by Using Laser Interference Lithography and Magnetic Analysis

J. H. Kang, S. G. Lee, H. M. Hwang, J. Lee and J. H. Song


We have fabricated polycrystalline Fe nanowires by using laser interference lithography without any mask. The width of the wire is varied from 161 nm to 458 nm. The pitch is controlled by adjusting the angle between the two laser beams. All the magnetic wires clearly show in-plane uniaxial magnetic anisotropy, but the anisotropy is affected by the ratio of the width to the thickness.
