Abstract

We produced (Rh) _{n ≈ 1100} nanoparticles by reducing Rh ³⁺ cations with alcohol solvent and, for the first time, investigated their magnetic properties. The X-ray diffraction pattern showed that (Rh) _{n ≈ 1100} nanoparticles had a face-centered cubic structure with a lattice constant of a = 3.813 Å. We measured the hysteresis loops and the magnetization curves versus temperature. Although small (Rh) _n<32 clusters are reported to be ferromagnetic, we observed the (Rh) _{n ≈ 1100} nanoparticles to be paramagnetic, as is the bulk metal, for the measured temperature range of T = 5 ∼ 330 K. Thus, (Rh) _n clusters will reach their bulk paramagnetism at n < 1100.
