Hysteresis Enhancement On A Hybrid Dy(Iii) Single Molecule Magnet/Iron Oxide Nanoparticle System

In this paper we report the synthesis and characterization of hybrid molecular-inorganic systems composed of superparamagnetic iron oxide nanoparticles coated with a shell of oleic acid (NP) and (Pr2NH2)(5)[Dy-12(OH)(16)(SALO)(4)(SALOH)(8)(NO3)(8)(H2O)(0.5)]NO3 (Dy-12) single-molecule magnets. The hybrid NP-Dy-12 system presents an enhancement of the magnetization hysteresis with respect to the isolated components while retaining the morphological characteristics of the parent NPs.
