The impact of the chemical synthesis on the magnetic properties of intermetallic PdFe nanoparticles
Source abstract
Abstract
Palladium rich Iron nanoparticles have been produced by a combination of two methods: the thermal decomposition of organo-metallic precursors and the reduction of metallic salts by a polyol. Herein, it is shown how the details of the synthesis have a striking impact in the magnetic and morphological properties of the final products. In the synthesis of these bimetallic nanoparticles, the use of high reaction temperatures plays an essential role for attaining good chemical homogeneity, which has proved to have a key influence in the magnetic properties. Magnetic characterization has been performed by Electron Magnetic Resonance and magnetization measurements, which have confirmed the superparamagnetic-like behavior at room temperature. No clear traces of magnetic polarization in palladium atoms have been detected. The combination of long term stability and homogeneous chemical and magnetic properties make these particles very suitable for a wide range of applications in nanotechnology.
