摘要：

Large-scale, 2D arrays of perfectly ordered magnetic nanoparticles were prepared using nanosphere lithography. We modified the preparation method based on a self-assembly of latex particles on water surface. Using such particles, with a diameter from 100 nm to 1 mum, it was possible to prepare arrays over 1 cm(2), with areas of over 50 mum(2) without any structural defects. By the evaporation of nickel or cobalt, periodic magnetic particle arrays were produced. To change particle morphology, annealing was carried out at 900 degreesC for 50 min. Modification of the distance between particles was also practicable by using double-layered masks. (C) 2003 Elsevier Science B.V. All rights reserved.
