Abstract (in english)
   The AMS within the Rayleigh law range was investigated theoretically, using mathematical modelling. It was revealed that the orientations of the principal susceptibilities are field independent and the shape parameter varies with field so weakly that this variation can be regarded as negligible from the practical point of view. In order to find out whether a magnetic fabric is due to single-domain or multi-domain grains, field- and frequency-dependent AMS should be investigated. The field-dependence of AMS is inherently a multi-domain phenomenon, while the frequency dependence is a single-domain phenomenon.
