| Abstract
| - Magnetic and electronic properties are investigated for Pd nanoparticles coated with a TTF-derivative (EDT-TTF(SCH3)(SC10H20SH)) and octadecanethiol organic mixed monolayer. The temperature-independent spinsusceptibility and spin concentration of Pd decrease upon the increasing proportion of the TTF-derivative inthe organic layer. With the introduction of the derivative, the ESR broad signal originating from the interiorof the Pd nanoparticles tends to vanish following the appearance of sharp signals due to the TTF radical. Thepresence of the TTF molecules enhances the charge transfer from the core Pd nanoparticles. The electronicstate of the Pd nanoparticles changes as a consequence of the contributions of both the quantum-size effectand the charge-transfer effect between the Pd core, TTF-derivative, and alkanethiol.
