“…The dependences of magnetic properties can be well approximated by the Rayleigh expressions. SMCs hence show a similar magnetization reversal behaviour in very low magnetic fields as already studied bulk crystalline or amorphous ferromagnets and soft ferrites [17][18][19][20][21].…”

“…Hence, many new applications of soft magnetic materials (e.g. low current transformers) include their use in the range of very low magnetic fields-the Rayleigh region [17][18][19][20]. Therefore the investigation of magnetization processes taking place in this induction range may provide valuable information since these processes are different compared to the processes at higher magnetic inductions.…”

The paper presents systematic analyses of a wide maximum induction range (0.001 T - 1.4 T) DC magnetic properties of iron-based soft magnetic composite materials by applying different methods to understand the specific features of magnetization reversal of this increasingly popular class of soft magnetic materials, including a hitherto less explored area of the Rayleigh region of very low magnetic fields, which has growing application potential in new, low-energy consuming electronic devices or ultra-low magnetic field shielding. The total permeability, coercive field and remanent magnetic induction were analysed in connection with the reciprocity factor and inner demagnetization factor and their relations to interparticle magnetic interaction, domain wall movability and predominance of individual magnetization processes. Their dependence on the magnetic induction and the properties of each sample were revealed and confirmed also by energy loss separation. The Rayleigh region analytical expressions for the coercive field, remanent magnetic induction, the ratio of irreversible to reversible magnetization changes and their percentages within the magnetizing cycle were used for soft magnetic composites for the first time.

“…In addition, the reduction of electric energy consumption of new electronic devices is a challenge for their strategic implications. In this context, the magnetic behavior of soft magnetic materials in the aforementioned Rayleigh area can provide useful information strongly connected with aspects on energy because such behavior is quite different on comparing with the magnetization curve at high magnetic fields [4,5].…”

We report on the structural and magnetic characterization of two nanocrystalline Finemet-type magnetic cores. The nanocrystalline structure developed after annealing the amorphous precursor alloy at 550 °C for 30 and 60 min of annealing time. Structural analysis carried out by means of X-ray diffraction providing useful information on the grain size mean and partial volume of the nanocrystalline phase. The magnetic characterization was focused mainly in the Rayleigh region which, influenced by the intergranular coupling, was found to be more efficient in the sample treated for a longer time with a finer nanocrystalline structure.
