Image of FIG. 1.
FIG. 1.

(Color online) Energy loss in the uniform sample per unit length, per cycle at five different frequencies, from 11.3 to 171 Hz, plotted vs amplitude of the applied magnetic field. The inset shows the bulk average critical current obtained from the loss data by inverting Eq. (1).

Image of FIG. 2.
FIG. 2.

(Color online) (a) The energy loss per cycle in the 20-filament sample, plotted vs amplitude of the applied magnetic field. (b) The specific loss in mm vs sweep rate. The plot includes all the data from (a). The loss data were normalized by a constant value of measured transport current . The straight line is an approximate linear fit corresponding to Eq. (5). Crossed lines in the center indicate the break-even point, where the coupling losses are equal to hysteresis loss.

Image of FIG. 3.
FIG. 3.

(Color online) The data for uniform and 20-filament samples are shown together. The plot includes the data from Fig. 1 presented as and from Fig. 2(b). For the uniform sample we have used the values of the critical current shown in the inset to Fig. 1.
