In the second one, the required sinusoid al quantity is magnetic field strength H. 2 THEORETICAL BACKGROUND Magnetic properties of soft-magnetic wound cores are usually assessed by using the so-called transformer method in which the tested core is equipped with two windings (Fig. 1).
An atom transfer radical polymerization route is developed for the coating of MnFe2O4 nanoparticles with polystyrene yielding the coreshell nanoparticles with size <15 nm. Magnetic studies show a decrease in coercivity after the formation of polystyrene shell, which is considered due to the reduction of magnetic surface anisotropy upon polymer coating. The MnFe2O4 nanoparticles as the Basis of Soft Magnetic Alloy-Uses of PermalloySoft magnetic thin layers are normally formed from 3d transition metal ferromagnetic elements such as iron, cobalt and nickel and their alloys, specifically NiFe and CoFe. The magnetic characteristics of soft magnetic thin layers are dominated by shape anisotropy, as the contribution of other anisotropy terms to the total energy is small.
Nov 14, 2017 · ABSTRACT. Magnetic measurements are indispensable for the characterization of soft magnetic material used e.g. in electrical machines. Characteristic values are used as quality control during production and for the parametrization of material models. Uncertainties and errors in the measurements are reflected directly in the parameters of the material models.
