CoxFe 1 − x纳米晶体在二氧化硅基质中制备的溶胶-凝胶法。通过X射线衍射（XRD）和透射电子显微镜（TEM）测量研究了金属前驱体的影响。通过测定77 K时N2的吸附-脱附等温线，研究了凝胶老化对孔隙率的影响。对复合材料样品进行了磁性测量。讨论了磁性。
CoxFe1−xnanocrystals 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 N2at 77 K. Magnetic measurements were carried out on the composite samples. The magnetic properties are discussed.
