Figure 12

Frequency dependence of (ΔZ/Z)max ratio for Co68.6Fe3.9Mo3.0Si12.0B12.5 rapidly quenched amorphous ribbon. Insets show field dependence of Δ(Z/Z) ratio for 15 MHz frequency: left inset–is given for large field interval and right inset is given for low magnetic fields (a). Frequency dependence of (ΔZ/Z)max ratio for amorphous ribbon without and with G-a gel. Green arrows explain definition of ΛΔ parameter. Inset shows better resolution image for (ΔZ/Z)max ratio for amorphous ribbon without and with G-a, G-b and G-c gels (b). Selected region of frequency dependence of (ΔZ/Z)max ratio for amorphous ribbon with FG-2 ferrogels, the thickener was xanthan gum (c). Concentration dependence of the ΛΔ* = ΛΔ(gel)–ΛΔ(ferrogel) difference for FG-2 and FG-4 ferrogels for frequency f = 60 MHz (d).
