摘要：
One of the basic problems of characterizing magnetic nanocomposites is to get information about the statistical distribution of the defects, and shape, and size of the particles. It is desirable to use quick, reliable and inexpensive magnetic methods. Information is usually obtained from the measurements of the DC remanence loop and switching field distribution (SFD), and the application of Preisach type hysteresis models. The discrete Fourier transform of the DC remanence curve is directly related to the SFD, and its application is illustrated on the example of magnetic nanocomposites of Fe particles embedded into a ZnO matrix, prepared by reaction milling.
