Abstract

Potential applications of superparamagnetic materials in magnetic storage and recording and magnetic manipulations in biological systems are discussed. A co-gel of silica and a Pd/Co cynaogel coordination polymer is prepared and on heating at 600°C, the material changes into a silica composite with embedded Pd/Co alloy nanoparticles. The X-ray powder diffraction (XRD) pattern of the thermally reduced Pd/Co on silica showed (111), (200), and (220) peaks slightly shifted towards angles from the position of (111), (200) and (220) peaks in pure Pd, indicating that Co is included in the Pd lattice. It is stated that the method can be further used in preparing a wide variety of supported transition metal alloy nanoparticles.
