Abstract

Abstract Co x Fe 1− x nanocrystals in a silica matrix were prepared by the sol–gel method. The influence of metal precursors was investigated by X-ray diffraction (XRD) and transmission electron microscopy (TEM) measurements. The influence of gel aging on porosity was determined with adsorption–desorption isotherms on N 2 at 77 K. Magnetic measurements were carried out on the composite samples. The magnetic properties are discussed.
