Hysteresis enhancement on a hybrid Dy(iii) single molecule magnet/iron oxide nanoparticle system†
Abstract
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[Dy12(OH)16(SALO)4(SALOH)8(NO3)8(H2O)0.5]NO3 (Dy12) single-molecule magnets. The hybrid NP-Dy12 system presents an enhancement of the magnetization hysteresis with respect to the isolated components while retaining the morphological characteristics of the parent NPs.
