Efficiency vs. for different values of the reduced applied field amplitude (), ranging from to in steps of . The frequency is fixed at (or for ). The linear response efficiency [Eq. (4)] is shown in dashed. Also shown are the two characteristic values of ; namely, the linear response maxima and the zero-slope threshold , which separate the regions of increasing and decreasing slope as departs from the linear regime.
Area and efficiency vs. the reduced applied field amplitude () fordifferent values of , with fixed . (a) Hysteresis loop area (); (b) efficiency (); (c) difference between and the linear response efficiency [Eq. (4)]; and (d) magnification of image (c) for small fields. Points were computed to Eqs. (7) and (8).
(a) Area and (b) efficiency vs. with fixed . The color scale is in arbitrary units, with blue and red denoting small and largequantities, respectively. The resolution is and .
(a) Next term, , in the power series expansion of [Eq. (7)], fitted from the initial values of up to . (b) Plot of vs. showing that all curves approximately overlap. The approximate expression given by Eq. (8) is presented in dashed.
Poli-disperse efficiency vs. for three values of the dispersion parameter . Mono-disperse curves are shown in dashed. (a) , (b) , (c) , and (d) .
