Abstract Dots of Ni80Fe20 were grown by electrodeposition on the top of a thin alumina barrier at preferential nucleation centers. The particle sites were induced by indentation with a conducting tip atomic force microscopy (AFM) on the alumina barrier (figure 1). Figure 1 shows regular spheres of Ni80Fe20 which all have practically the same size. The size of the dots (sphere) can be controlled by varying the time deposition. The behavior of the current has been confronted to a theoretical nucleation-growth model. Using a conducting atomic force microscope, we characterize the resistance of the defects on which the dots nucleate. Preliminary electrical transport measurements were performed on the permalloy dots.
