Losses measured up to 1 GHz at and in a Ni–Zn ring (diameter 10 mm). The low-frequency curve is obtained by the fluxmetric method (open symbols) and overlaps with the curve descending from Eq. (1), with and measured up to 1 GHz with the transmission line method. Dashed lines: hysteresis loss component .
Real and imaginary relative permeability components vs frequency measured in a Mn–Zn ferrite ring sample at peak polarization and effect of an applied saturating transverse field .Symbols: fluxmetric method. Dashed lines: transmission line method.
Wideband energy loss behavior in a Mn–Zn ferrite at and its dependence on the transverse field strength . The loss increases with , in spite of the progressive elimination of the d.w.s. is little affected by in the upper frequency range. The dashed line is the predicted classical eddy current losses.
Experimental energy losses in a Mn–Zn ferrite up to 1 GHz for . Open symbols: experiments. Thick continuous line: predicted . The dashed lines show the predicted eddy current loss contributions.
