| dc.description.abstractEn | The usage of micro or nanorods is steadily increasing in various applications from fundamental research to industry. Therefore their geometrical, mechanical and eventually magnetic properties need to be well determined. Here, using an optical microscope equipped with magnetic tweezers, we report an experimental procedure to obtain all these information on a single magnetic rod. In particular, we measure the magnetic susceptibility [small chi] by analyzing the deformation of a rod submitted to a uniform magnetic field. To do so, we refine a theoretical model which takes into account the variation of [small chi] with the internal field. We prove experimentally that this model yields consistent measures, at any value of field strength and incidence angle. From the combination of the different measurements, we also deduce the number of iron oxide nanoparticles which are embedded within the polymer matrix of the superparamagnetic rods under study. | |
