Surface Magnetic Properties and Magnetization Dynamics of Magnetite Nanoparticles Doped with Platinum Ions
Abstract:Magnetization dynamics and surface magnetic properties of the magnetite nanoparticles doped with platinum cations are studied on the microscopic level using EPR spectroscopy. The composite samples are formed on the steel surface contacted with Pt-containing water solutions under the rotation-corrosion dispergation conditions. Increase in Pt part in the structure of nanocomposites is accompanied by the corresponding shift of the EPR lines towards higher energies. Absorption EPR spectroscopy demonstrates specifi… Show more
