Abstract
This work presents the synthesis and investigation of Prussian blue and its chromium analog nanotubes obtained inside porous polycarbonate track etch (PCTE) membranes by electrochemical deposition. The process yielded nanotubes with outer diameters between 50 and 200 nm and thicknesses of approximately 30 nm. It was found that decreasing nanotube diameter had little or no effect on magnetic properties (critical temperature and coercivity). Additionally, the growing process and the basic properties of double-shell nanotubes are described. These double-shell structures show a two-component magnetic behavior. By using the theoretical model, it is possible to decompose the hysteresis loops into the base constituents and derive the relative concentration of each counterpart.
