Colloidal Synthesis of NixPt1−x Nanoparticles with Tuneable Composition and Size

NixPt1−x is the missing link in the series of magnetic alloy particles. We report here on the first high‐quality synthesis of this nanomaterial. Although the chemistry of the Fe, Co, and Ni compounds is usually similar, distinctive differences are found in the nucleation, growth, and shape control o...

Description
Summary:NixPt1−x is the missing link in the series of magnetic alloy particles. We report here on the first high‐quality synthesis of this nanomaterial. Although the chemistry of the Fe, Co, and Ni compounds is usually similar, distinctive differences are found in the nucleation, growth, and shape control of the respective nanoparticles, and first magnetic measurements are presented. The image shows star‐shaped agglomerates of nanoparticles.
