Formation of ferrimagnetic films with functionalized magnetite nanoparticles using the Langmuir-Blodgett technique.
The formation of ferrimagnetic films of 39 nm magnetite nanoparticles functionalized by stilbene derivatives has been studied using the Langmuir-Blodgett technique. The stilbene moieties are grafted to the particles either via a phosphonate or a carboxylate group; in both cases the nanoparticles display similar isotherms although the microscopic initial and final states of the films are different. Two different mechanisms of film formation are proposed, based on the inorganic-organic bond stability.
