A submicron semiconductor Hall magnetometer was used to study magnetization of an array of 16 elongated iron nanoparticles with diameter of ∼7 nm and height of ∼100 nm. The magnetization hysteresis curves and the angular dependence of switching fields were also examined. It was shown that the magnetization reversal in these cylindrical nanoparticles cannot be described with a single coherent rotation mode.
