In this paper we present a study of the separation of phases in multi-phase alloys. The proposed technique is based on the hyperbolic model of magnetization. In this work the normal magnetization curve of the model was fitted to the measured one. It is possible to decompose the magnetic phases of alloys and determine their magnetic properties separately by using the determined model parameters. Experimental verification was carried out on a transformer like setup, constructed from layered samples. The samples were constructed from elements of strongly different magnetic properties. The results given by the model are in an excellent agreement with the experimental results, giving justification for the proposed method of decomposition. The proposed method could become a vital tool in magnetic investigations.
