Magnetic force microscopy (MFM) observation was carried out on fabricated nanodot arrays. MFM tip induced magnetization effects were clearly observed in ferromagnetic elliptical nanodots varying in material and aspect ratio. Fe-Cr dots with a high aspect ratio show reversible switching of the single domain magnetization state. At the same time, Co nanomagnets with a low aspect ratio exhibit tip induced transitions between the single domain and the vortex state of magnetization. The simple nanolithography is potentially an efficient method for fabrication of patterned magnetic arrays. 한국자기학회 Magnetic Force Microscopy (MFM) Study of Remagnetization Effects in Patterned Ferromagnetic Nanodots Article 2 Journal of Magnetics, v.10, no.2, pp.58 - 62 Journal of Magnetics 10 2 58 62 kci ART000964146 nanodot magnetic force microscopy remagnetization domain lithography nanodot magnetic force microscopy remagnetization domain lithography
