In this paper we present anomalous Hall effect analysis from very thin Co (0.5 nm) film, Co/Pt multilayers and large areas of nanosized dots as well as from a few magnetic dots having a diameter of 120 nm. The dot array is prepared from Co/Pt multilayer by using laser interference lithography (LIL) while the Hall crosses for measuring a few dots are prepared in combination with focussed ion beam (FIB). The hysteresis loops from a few dots are showing significant Hall voltage jumps corresponding to magnetic response due to an inhomogeneous reversal mechanism because the intensity of the jumps is smaller than the expected value from a total magnetization reversal of one dot.
