Synthesis of magnetic nanoparticles via pyrolysis of carbon precursors and the effect of diamond powder on their magnetic properties

This study explores the implementation of diamond powder (1~10 nm) in the synthesis of magnetic nanoparticles (MNPs) coated by graphene with a focus on their morphological, structural, and magnetic properties. To obtain a deeper insight into the influences of impurities in graphene matrices on the magnetic properties of synthesized by pyrolysis carbon precursors. Particularly, the impact of diamond on the magnetic saturation and coercivity properties of hydrogen-rich materials. Of which the hydrogen to carbon ratio (H/C) is a minimum of 1, but ideally higher. This research highlights the importance of diamond as a novel material for its various applications, from electronics and radiation detectors, to spintronics and quantum information. Initial magnetization measurements indicate that the samples—high density polyethylene—without diamond powder are paramagnetic. However, samples with diamond powder (10wt%) have shown an increase in the saturation and coercivity. Moreover, we aim to explore different concentrations of diamond powder, pyrolysis temperature and time. As well as study different materials like ferrocene as we expect diamond powder to also increase its coercivity and saturation. With the aim of characterizing the ideal conditions for diamond to effectively be implemented in the further study of MNPs.
