Abstract

The structure and size determination of synthesized magnetic nanoparticles and morphology investigation of nanocomposites containing magnetic nanoparticles have attracted a lot of interest. One of the best ways for characterization of these particles is using a magnetic force microscope equipped with a magnetic probe. In this research, a simple and reproducible technique for manufacturing magnetic force microscope probes with the aid of multiwall carbon nanotube using DIELECTROPHORESIS method has been developed. Suspensions of certain concentrations of carbon nanotubes in Ethanol–Deionized water solution and the surfactant sodium dodecyl sulfate have been prepared using an ultrasonic. In order to attach carbon nanotube to the silicon-made atomic force microscope tip, the effects of several factors such as voltage, frequency, the angle between tip and electrode, and finally the tip geometry should be investigated. To facilitate injection of CNT solution into the space between gold-coated silicon probe apex and electrode plate, the distance between them was adjusted to 30 micrometers.Experiments for investigation of voltage effect revealed that the optimum voltage to attaching CNT to the tip apex is 13 volts. Magnetic probes were covered with cobalt and then magnetic samples were imaged using these probes. The results were compared with images obtained from commercial probes and it was found that higher resolution images can be obtained with constructed probes. The fabricated tips have greater longevity that can be attributed to the elasticity and higher mechanical and thermal stability of carbon nanotubes.
