	abstract = {Herein we present the simple fabrication of magneto-polymer nanostructured composites. Specifically, large aspect ratio polymer-based magnetic nanotubes and nanorods have been prepared by means of wetting nanoporous hard templates with loaded polymer melts and solutions, respectively. Morphological characteristics of both one-dimensional composite nanostructures were evaluated by scanning electron microscopy. Moreover, important parameters of the materials such as elemental composition and distribution of the metallic elements were determined by means of X-ray diffraction, and Rutherford backscattering. The different confinement topology of the nanoparticles within the nanorods and the nanotubes leads to a stronger (i.e. ferro-) magnetic response of nanotube arrays, as determined by magnetometry. The magnetic measurements also allowed estimating the concentration of nanoparticles by means of properly fitting experimental data to a sum of different magnetic contributions to the total magnetic moment. The morphological, structural, compositional and magnetic characteristics of nanotubes and nanorods are related to the different wetting approaches used. It has to be noted that, to our knowledge, we present here the first example of nanoparticulated polymer-based composite nanotubes synthesized from the melt, which, indeed seems to be at the origin of their high morphological and compositional quality. The potential of Rutherford backscattering spectroscopy for characterizing soft composite nanostructures has to be also remarked.},
